  1. Afternoon
    My 17 month old Great Dane goes crazy and tries and has bitten someone when they have approached him. He does not like strangers or busy places. Please help?

    • initially put constraints on the dog’s activities. do not let it out without leash. look for probable causes inducing such behavior. the dog might be suffering from some ailment check if your dog is getting optimum rest and feed.

    • You should also take note on how the dog is being approached by the person, the person could be the issue not the dog. Strangers should never approach your dog, the dog should be allowed to come to them or you should introduce the dog to this new person once the dog is calm. During the introduction the new person should use gestures that suggest they are asking the dog to get to know them an don’t forcing themselves on the dog. Strangers should never try to pet a unknown dog’s head, they should slowly extent their hand in front of the dog and allow the dog to come to them when the dog is ready. They should pet the dog’s chin (once the dog is ready to be touched). Rule of thought, strangers should keep their hands where the dog can see them, petting a dog on the head can make the dog uneasy because someone is reaching over their head were they can not see. During the introduction the dog will let you know if they feel comfortable with the new friend through body language and growls. Listen to your dog and do not force them to make friends. Do be sure to let the dog know aggressive behavior is not tolerated in a constructive way and not a destructive way such a yelling and hitting. Remember to praise the dog when they properly comply.

  2. Yes i got a blue great dane when she was a puppy my problem is when she gets a hold of something that is not good for her i try to take it from her well to put it short the other day she got a piece of pizza off the kitchen table and i tried to get it from her and she attact for the 3rd time since I’ve had her she bit my arm so hard i thought i might need stitches what should i do.

    • The dog needs to be taught how to release, you should never have to take anything from her. This can be done though playful games such as fetch. You can teach the dog to “Drop it” followed by “Leave it”. This is a fun way to teach two important commands to your pup. Once this is taught, these command can be used in situations such as the pizza incident. With a stern voice you should be able to tell her to “Drop it”, you should follow up with “Leave it” if she tries to retrieve the object before you can get it. When you tell her to “Leave it” she should back away allowing you to remove the object without her coming after you or the object.

  3. We have a 17 month old great dane that bit our grandson, and broke skin. He was trying to help his grandpa get him out of a room thato he was trying to sleep in. The very next night our grandson tried to take his leash off and he snapped at his face. What has us puzzled is when we saw this happening here didn’t do anything to the dog. In fact it took us by surprise. With all the kids around this child is probably the most laid back kid of all them. Normally this dog goes nuts when he hears kids, because he knows it’s playtime. He has growled at a couple adults in the family and couple of times. What could cause this sudden behavior ?

    • I have a great dane pup that is 10 months old, he does not like small children. Its only the ones that r eye level to him he gets aggressive towards them. Need help on how to be able to stop this.

  4. HELP! I have a 6 month old Dane (our first dane but have had several dogs). We also have a 13 yr Coon Hound. Our Dane is showing food and territory aggression toward our Coon Hound suddenly. We feed them separate in different rooms and I allow a few minutes after they are both finished to pick up bowls and finish any left over crumbs. When I bring them back together my Dane watches the Coon Hound (who instinctively sniffs around) and attacks him and bites him. I have even extended the time before releasing them from their rooms but she still goes after him. The tension around feeding time is so high now and I don’t know what to do.

    • The principal thing to do is to separate the Dane form Coon. Do not let the Dane see the other dog after eating or any other time.
      Besides, try to find possible tipping point leading to the dog’s aggressive demeanour.

  5. I re homed a male 3 year old, he is laid back but has shown aggression when you tell him not to do something, today he backed my 7 year old daughter into a corner and was growling and showing his teeth, I got him away from her by calling him. Then he started doing the same to me! I didn’t hit him or scold him just said “hank come in here” I did it calmly because I didn’t know what was about to happen. I need help in the worst way !!!

    • The dog entails training you can either train it yourself or take assistance from professional dog trainer as the dog is an adult already. If you are inclined to train the dog yourself kick off training from initial step i.e. obedience training. Meanwhile it is better to put the dog on leash until it gets fully trained.

  6. My Great Dane is starting to be aggressive towards my son. My son and him are together most of the time. They sleep together, lay on the couch together, and usually are always near one another. Our Dane is now acting out when they go outside. He started a couple of weeks ago growling and snapping at my son when they are in the fenced backyard. My son can be walking and the dog will get in front of him and try to bit/growl at him. Is he becoming aggressive towards him now for some reason we just aren’t aware of. We have 3 other children and he doesn’t do this to them. What can I do to help the situation?

    • First of all try to figure out why the dog is getting aggressive this way? There must be something bothering the dog as mentioned in the article. If everything is fine than it means that the dog is regarding your son as a ‘bad thing’. As this sudden aggression is only directed towards your son then the boy might have offended the dog. Well this could be unintentional on your son’s part as kids are just playing and having fun. So here is what you can do;
      From now on supervise your son and the dog whenever they are together. Do not let your son too close to the dog.
      Ask your son to give the dog treats so that it may regard the boy as a ‘good thing’ instead of thinking it as a danger and ‘bad thing’. Which could be the reason for the dog’s aggression.
      If the dog continues growling, you may consider taking your son with you when you are feeding the dog. But remember to keep distance. So all in all you need to change the dog’s aggression into ease and comfort towards your son as you said that the dog is fine with other people.

  7. Hi Alice. I have two female Great Danes. We bought them when they were both pups, and they are now 2 and a half years. Both have been neutered before the age of 1. The routine with both involved sleeping inside the house at night on their blanket in the lounge, whilst playing music, and the next morning they would wake up once we wake up and go outside with a treat. The remainder of the day they would roam around the property until the kids and I got back from work at 5. We’ve recently moved back to my ex husband so that the kids can stay at one place during the lockdown. , and have been here for a month now. The dogs adapted very well, especially with the yard being much bigger, and the palisades allowing them to see more activities.. We still follow the same feeding routine and playtime with them as when it was just me and the girls, they still do their wolf/howling when people walk by, and at night chase each other around. The only thing that changed apart from the new environment, is that they are not allowed inside the house, so they sleep outside, in front of my car, same blankets that covers them as per previous routine. Two nights ago my child was playing outside with them, and the mistake she made was using the blanket as a toy. The dane who usually does not play fetch, is glued to the blankets. For the first time they had a go at each other, not releasing, as we had to pull them apart. Amazingly the only injury was a bitemark above the eye to the dane who prefers her blanky. It’s very clear that the other dane established dominance, whereas she usually was the submissive one on the old property. Since then, the two are fine with each other’s when I am not outside, but as soon as we go to tuck them in at night, they make their scorpion tales. They do submit when I lower my voice, but I’m noticing that they begin taking longer to really listen to me and instead keep staring at each other. My danes are really so well behaved, during the day they seem normal, and I’m taking care to just walk around so that both can follow me, rather than me following them and giving attention to whomever asks it first. Any advise on how we can stop the aggression from excelating? I’m thinking of washing them and the blankets to get the stinch from 3 night ago out the way. But I don’t want to ignore any signs, and there are definitely a change in behaviour, which concerns me as they both still give so much love and remain obedient to any instructions. I don’t yell at them, they are too sensitive and are used to us talking to them alot as if they are part of the children, and they interact accordingly. If I tell them wait, they will wait with the door wide open. If I tell them okay you’re allowed inside, they run towards me immediately. When it’s feeding time, they will allow me to take food from the bowl whilst they are eating. But the moment they get too close for comfert to each other, the signs begin. I woul appreciate your take on this. Regards, Elaine

    • Elaine, your dogs are quite well behaved and its all due to the training. Well i would say that you do not need to worry too much. Given the changes in their environment the dogs’s might show difference in their behaviour over all. As far as the incident is concerned, its not the dogs’s fault. It was told to do so, remember ‘using the blanket as a toy’ or not even the other dog’s. What you have mentioned later, is basically the effect of the incident on the dogs. The way you are handling the dogs is right just keep with it include some obedience training as well. Try to keep the dogs in your sight in the coming days to know if anything considerable happens.

      • Hi, we have 10 week old Great Dane male, , he is very shy to new people and has a tendency to growl at strangers. We want to fix the problem right away before it becomes a problem in the future, what should we do?

          from beginning and it was ending to say “Good buy” to him, he protect me and watching some people who was passing as if they will not hurt me and one day he bite as my protection. We play in the dog park with the other dogs,on the beach it was ok , but I realized some more changes after he was 3 y. old and I realized it start after rabies and other vaccination.

  8. What can i do my dane is 3 and she is so aggressive to peopple and strangers im to point of rehoming her it has always been me and her a d family but let someone walk up to door even knowing them she wants to stand guard any solutions

    • You might need to get the help of a professional trainer. As the dog is already three, it will not be easy to correct its behaviour on your own. If you are considering to train it on your own, first evaluate the overall behaviour of the dog. If it is mainly obedient than you can resort to correcting it every time. For example, whenever you do not want the dog not to stand on guard simply ask it not to ‘Lucy come to me’. Besides, you can also offer the dog its favourite toy or treat to make it come to you.

  9. I have had my Dane since he was 12 wks. He was doing great, no issues. After I had him neutered at 18mos, the vet suddenly said he has agreession. ( news to me). After that surgery, nothing has been the same. He is horrible to take to the vet( we have now moved and switched vets). He just turned 3 and I have my hands full. He is showing aggression towards other dogs, me and my husband, over little things. Like putting I. His collar to go out, petting him normally, etc. yesterday he dragged me and my husband off the pavement to a chihuahua that was tied out and he literally pinned this dog to the ground. He has always had issues with certain breeds, such as a German Shepard. But plays off leash beautifully with pit mixes and Dalmatians. Today he definitely has me worried, as I went to collar him, he pulled back and growled. He is in stellar health, and this is quite a shock for me, as he has always been my sweet boy. I’m going to start using some of the tips from the article, praying we can come back to a calm relationship. Great article btw.

  10. My 2.5 year old girl is only showing aggression to males young and old.
    We just recently moved, and have had a few parties this summer. She seems to bark and run after the young boys playing in the yard and some of the older males that are intimidated by her. I have had her since she is 7 weeks old, and when she came home and for another year after it was always just myself, my daughter and her.
    Moving in with my boyfriend, she has never shown aggression towards him.
    Sort of lost and confused on how to fix these issues with her.

  11. My daughter had a beautiful Harlequin Great Dane from a puppy he began to show signs of aggression around 1 + years old, he was a very loving dog to all the kids but soon he was growling and then tried to attack a guest at the pool. I remember how protective he was with me once when I fell he came over to help me when he could not get me up he gently turned around and sit down on me, and then allowed me to climb up on him till I could stand! Not soon after that my daughter was kenneling him because of guest, he turned and attacked her, the vet soon neutered him and after surgery he attacked them too, they were going to put him to sleep when a vet assistant who was a dog trainer asked for him, and the vet trainer who was single and had no children took him for one year he had an adoring dog, yesterday I heard what happened! Last week (JR the dog) attacked him while they were sleeping at night together and tried to kill him, JR was shot as he sliced open the young man’s head! WHAT IS WRONG WITH GREAT DANES????

  13. My great dane is about 1.5 years old. I have 3 other dogs that stay in the same house as her. A malinois, pit mix, and chihuahua. She gets along great with them and they all play. But when I take her for walks she becomes aggressive with my friend’s dogs. They are both pits. They can walk with each other fine but if we stop and they go towards her she growls and barks and shows her teeth. She bit my leg one time when I stepped between her and my friend’s dog trying to calm it down. Of course I always keep her on leash so she can’t really hurt them. I just don’t understand why she’s aggressive with them and not with my dogs at home. She seems scared and nervous around them even if its just one of the dogs with her. And she hides behind me with her tail tucked and her hair spiked until we continue walking and she sees its okay. She walks next to them both fine (one is a male and one is female) its when we stop that there is an issue and when we first meet up. Also she is the same way with other dogs walking passed but again she is completely okay with my other dogs at home. I dont know what to do. She never used to be this way.

    • She is also a complete lover to all people only barks at new people entering the house or walking around our yard. She loves to run up to people without a dog when we go for walks. And she loves her cuddles and pets. Bigger lap dog then my chihuahua.

  14. We have a almost 8 month old male blue Great Dane. He has been very guarded around his food and toys or anything he has found such as a wrapper or shirt. He will growl , snap , nose crunching and attempt to bite .
    He was also mounting my 12 yo daughter and my husband.
    Last week he bit my 15 yo daughter drawing blood twice ( unprovoked).
    We had him neutered as the vet said emergently to try and lower the testosterone. They gave us medicine to sedate him and keep him calm during recovery and it made him wilder .
    Today he threw up after lunch and was guarding his vomit and growled when you come near him.
    Blood work is normal. We have contacted a trainer for an evaluation next week but I am scared for my kids.
    Any suggestions would be appreciated

  15. Oh, dear. Some of these stories make me cringe. My Great Dane male is 11 weeks old. Full disclosure, I am retired and rather inactive. He does like to spend time with me and is aggressive to my other 2 dogs, resulting in my yellow lab to voluntarily want to live outside. I was initially successful with potty training but since I have extended outside time to include playtime in an effort to tire him out, he’s gone backwards and soils inside now. The only command he responds to is sit. He can now reach most things on furniture whether sofa or tables or beds. When he bites me I first command no and try to push him away. He is already stronger than me. I then take the toy (me) away from him, but he bites me the entire time I am standing. He lunges at my my head, tears my hair and bites my scalp, ears and neck. He has not yet gotten my face. I am exhausted and in tears most nights. Thank you for your ears!

  16. We have had our male Great Dane for 2 months. He’s 4+ months old. He’s super lovable but I find that he snarls, rolls eyes and bites adults with no reason. Vet just tells us he’s a puppy. Unfortunately I’m getting nervous being around him as he gets bigger. What can I do?

  17. Hi alice duke is a 2.5 yr old male intact black dane and when he was 6mos we had him walking at a. Park and a truck with a dog in the bed drove by us as we were walking and the dog in the truck was aggressively braking as they drove by and scared the scrap out of duke and since then he has bark at people dogs and even tries and pull us towards them it as slowly gotten worse to the pio t we don’t take him any where anymore and I have been wanting to get him neutered but ran into problems with he has a heart murmur so at this point he stay in the house or on the porch with me and still bark at Amazon drivers / mailman and even the teenage kids when they get home amd he patrols the the porch and when he see a coon or possum he goes crazy barking and jumping and when we give him a command he’ll start to do it for a split second and then gets drawn back to it please let me know what you think

    • Firstly, you are doing the right thing by keeping Duke at home.
      Secondly, the incident must be the instigator in your case. But it is not just the dog in the truck, I think some other unusual thing might be happening around at the moment that scared the dog. I wonder if it was the first time it saw a truck or a barking dog.
      Thirdly, as you said ‘he’ll start to do it for a split second and then gets drawn back’ this indicates some lack of training as well. The distraction it is having is much more influential than your command. Which is a huge problem for any dog parent.
      Here is what I can suggest you:
      Start obedience training right away.
      Practice some distraction training as well. You can start off with a place with least or no distractions at all. Give the dog a command and see how much the attention it pays.
      And gradually let the dog exposed to the distractions rather than staying there all the time during the training. You can also get the help on how to deal with distractions from here.

  18. I am a dog sitter for a Blue Great Dane; I have been trying to get the dog to understand that I am safe and should be trusted.

    The owner got him during the COVID-19 shutdown, which caused him not to be sociable with many people. He only trusted his family members; I took care of his older sister (who pass away last December) who trusted me since she was a puppy.

    He is going into protective mode toward guests and myself. I would bring treats to get him to stop going into protective mode. I need a remedy to get him to stop growling and trust me based on my voice so that his family can go on vacation.

    Many family members and I feel like we should been there since the beginning to get him to trust us.

  19. I have a 1 year and 5 month old female great dane. I also have senior black lab and shihtzu. The dane seems to always try to go after the shihtzu for no reason at all. She punctured her before. And now recently she has bit my 8 year old daughter again for no apparent reason. The dane was laying by me in the couch and my daughter got up to exit the room and the dane juat jumped up and started biting her in the shoulder. I can’t figure out the sudden issue. Now I have to keep her on leash alot in the living room because she will try to growl and lunge when she comes in the room. Nothing has really changed from before so I don’t know what to do.
