Why is my aggressive puppy biting, destroying, and peeing inside?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | 8 months and 6 days old | 68 lbs

My dog is being very aggressive to the point he's biting me with bruises regardless how good he gets treated.Also spoiled plus he has a problem holding in his pee and he's destroying everything including ripping the clothes that's on you. One minute he's well-behaved the next minute he snaps you could be sitting down doing nothing and he still does.

Aggression is complicated because it can be playful aggression, dominance, possessive or anxiety. Unless you are very familiar with canine behavior, training and body language, this is a situation that requires a dog trainer. The trainer will watch Trevor’s behavior and then will teach you how to modify your behavior to change his. You should also get a few books about dog behavior and training so that you can learn how to recognize the body language as this will help. Neutering Trevor can also help to decrease unwanted behavior. I hope this is helpful and please feel free to post any additional questions.
