My 9-month-old dog is aggressive, bites, and disobedient. What to do?

Updated on September 23rd, 2025

Pet's info: Dog | Rat Terrier | Male | unneutered | 7 months and 30 days old | 10 lbs

Hello, i have a rat terrior around 9 months. We have had him for a few weeks now and can be very sweet at times but he tends to come off aggressive, not sociable at all with other people or dogs and has bitten our young children a few times from them bothering him or wanting to play with him. He is very disobedient and getting worst as the days go by... I'm at the point where I think he needs to be rehomed. Is there anything you could tell me that might help us with our pup? Thank you..

I am sorry you are struggling with Chico. I would highly recommend bringing a trainer into the house after making sure a physical exam by a veterinarian is normal. Behavioral issues/ training takes a lot of time and patience. I feel having someone come into the home and observe the situations where he is anxious and aggressive will help. Also recommend getting him neutered as soon as possible.
