My dog is aggressive, biting, jumping, and peeing inside. What to do?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 1 year and 1 month old | 31 lbs

We adopted a beagle/hound mix he's 1 yr old. He tends to get very aggressive,starts to bite,rough housing, jumps on people. He(Murphy) is house trained but at times he will just urinate somewhere. It's his aggression(if that's what it is) that makes people, not to comeover. He's like that towards us also. I know he's still a puppy we do take him out to run in the yard and play. Any thoughts on what I can do.

I am afraid that unless Murphy is properly assessed and trained, he is a bomb waiting to go off and very likely will hurt someone. I suggest you make an appointment with your vet to have him examined in order to rule out any physical or health reasons that feed his aggression. Then get a recommendation for a veterinary behavior specialist (or you can find one here: https://www.dacvb.org/ ) and have Murphy assessed and then the behaviorist will work with you to alleviate the aggression, and the urinating issue (which is likely a dominance issue). It is best to deal with this while he is a puppy.
