My 2-month-old aggressive puppy bites my dog and me. What should I do?

Yes it can be normal at this age, but you have to stop the behavior now or it will get worse as Capi gets older. Unfortunately, this is a serious problem - aggressive behavior like this (assuming it's true aggression and not rough play) is very abnormal in such a young puppy. To have the best chance of growing up to be relatively normal, puppies like this need early behavioral intervention from a professional. I would strongly recommend making an appointment with a veterinary behaviorist as soon as possible for a in-person evaluation of your puppy. He/she can give you a much better idea of whether this issue is "fixable", in the sense of having a relatively normal dog when he grows up. They will also help you put together a step-by-step training plan to work on the problem, and give you very specific management instructions to make sure everyone stays safe.

That is a lot going on and it sounds like Oggy would benefit from a visit with a trainer or veterinary behaviorist in your area, especially if she is being aggressive to the point of bruising or drawing blood. Aggression usually looks very different from play/exploration biting and can include low growling, stiff bodies, showing the whites of the eyes, hair raising on the back, baring teeth, and then nipping or biting. This is unusual in a puppy of this age, so if it is happening, it is best to seek professional help in person ASAP since it is a complex issue that needs to be worked with. If the nipping is just puppy nipping, and she is also chewing on lots of things, it could just be normal puppy behavior and a puppy kindergarten/training classes is a great way to establish some ground rules and get used to interacting with each other in a positive manner. I'm also including some articles on general puppy nipping/chewing that may help as well. https://www.petcoach.co/article/puppy-biting-nipping-of-hands/ https://www.petcoach.co/article/puppy-biting-when-does-it-stop/ https://www.petcoach.co/article/chewing-in-puppies-how-to-control-it/ https://www.petcoach.co/article/6-tips-to-help-prevent-destructive-chewing/ https://www.petcoach.co/article/how-to-choose-a-dog-trainer/

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Bruno. When a puppy shows aggression, I immediately advise neutering him to remove the male hormone-driven behaviors. I would advise taking him to your veterinarian for their opinion also. He may have some medical reason for his sudden onset of aggression. Your vet can gather a history, perform an exam and then offer a diagnostic/treatment plan based on their findings. Possible tests include fecal/blood/urine tests and x-rays to look for underlying medical problems that could cause aggression. If a behavioral problem is suspected, then neutering, behavior modification, and drug therapy can be tried. I wish you good luck with Bruno

This can be very common behavior for young puppies. It is important that you initiate training with your dog now so that his aggressive tendencies do not continue into adulthood. Somethings you can do to discourage his nipping and aggressive behavior are to try and redirect his aggression by giving him a toy to play with and bite on instead of using your hands and fingers. Also, when he missed behaves firmly tell him no, put him down and walk away and ignore him for 2 to 3 minutes. After that time you can start playing with him again and if his bad behavior returns ignore him again. If you continue to do this he will quickly learn that when he misbehaves you will not pay attention to him so he should stop the bad behavior. It would also be beneficial to start training him with basic commands like sit, stay, and come. This will help establish your role as the dominant one in the relationship. Also be sure he is getting plenty of exercise by taking him on 20 to 30 minute fast-paced walks at least 2 to 3 times a day. This will help drain some of his energy and make him be able to focus on training with you better. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. That’s the one.

Oh dear! Growling when you pick her up is a major red flag for future problems in a puppy this age - this is not normal, and needs more help than just socialization. From your description, it's hard to say if her behavior with the other puppy is normal play or aggression. I would strongly recommend making an appointment with a veterinary behaviorist who can evaluate her in person and help you put together a plan to work on these issues - it's best to do this as soon as possible, since early intervention gives you a much better chance of being able to change this behavior before she grows up. I'm not sure what part of Canada you're in, but your regular veterinarian should be able to help you find out where your nearest board-certified veterinary behaviorist is so that you can make an appointment. In the meantime, I would try and avoid doing anything that tends to make her growl - instead of picking her up, for example, use treats to encourage her to come to you. I would also not recommend any kind of punishment for this behavior, as this has a high risk of making things worse over time. The behaviorist can help you identify what kinds of situations tend to trigger the growling, and will put together a training plan to work on this issue.

If you feel like your puppy is weaker than her should be at this age then I recommend taking him to the veterinarian to be examined. He may have intestinal parasites (very common in young puppies) or could have something more serious like parvovivrus. You should also make sure he is fully vaccinated. Your veterinarian can give you a schedule of when he needs what vaccines. He should also be vaccinated for rabies at 12-16 weeks of age. Your puppy should be eating a large breed puppy food. This will ensure he gets all the nutrients he needs. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

Congratulations on your new puppy! It takes some time for puppies to learn to mind their manners. I recommend making sure that Percy has plenty of toys to chew on as his adult teeth are coming in. As you are playing with Percy and he starts biting, you should stop playing and tell Percy "no" and only begin paying attention to him again once he is calm. I hope this helps and am happy to answer any other questions you may have about Percy!
