How to stop my dog barking aggressively at visitors and on walks?

Thanks for using Petco Pet Education Center, formerly Petcoach! These types of behavior can improve though this does require in person training with the help of a qualified dog trainer. I would encourage you to contact a dog trainer that can work with you and Bruno in person to really take care of this behavior. The sooner these behaviors are dealt with, the more likely it is that you can improve and resolve them. Good luck and have a great day!

Thanks for using Petco Pet Education Center, formerly Petcoach! Almost any behavior can be resolved with training and behavior modification. I would highly recommend you consider contacting a local dog trainer who can work with you in person as that is needed. This should work but it will take time and persistence and of course a professional working with you both. Best of luck!

This is a very tough situation. If you're serious about Max getting better, I would recommend scheduling an appointment with a veterinary behaviorist to get to the bottom of the problem. This is a good place to look: https://avsab.org/directory/ While you're waiting for your appointment, make sure you aren't punishing him for this behavior (because punishments can make it worse), avoid all situations in which it occurs, when you are on walks take really great treats with you and use them to keep his attention on you if you have to walk pasted another dog (but avoiding all together would still be better). Your dog will likely need a combination of behavior modifications, training, and medication and he may never be a totally normal dog. Wishing you the best of luck. Thanks for using PetCoach

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. I agree with you, the discipline has not been handled correctly. There are other, better ways to discipline a dog but at this time it is going to be difficult to correct without a professional trainer. Does she have fear aggression? I don't know because I have not witnessed the behavior myself so I can't say for sure. You need a professional dog trainer to come to your house and see the dog's behavior and how the dog interacts with everyone in the house. Only then can they make recommendations on how to correct the problem. Sometimes you need to work concurrently with a veterinarian as behavior modification medications may be needed in the beginning of the re-training. I'm sorry I do not know where you are located so I can't really recommend a trainer. I suggest you call your vet for a recommendation. Hope this helps. Best wishes.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. I would recommend using corrective collars like a pinch collar or gentle leader. These can help stop the pulling behavior. You may also look into the low voltage shock collars. These collars emit a small shock that is similar to being snapped by a rubber band. You can use this to correct the behavior and these collars can all be found online or at your local pet store. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
