What Can I do for my puppy that is showing signs of aggressiveness?

Our question this week was:

My 9 mo. old Maltese is a precious puppy. Then out of the blue she changed and is very aggressive. We have to muzzle her to bathe. Any suggestions?

Thanks for your email and question. I’m sorry to hear about your puppy’s aggression. And she is only 9 months old. This is a problem and has the potential to be a BIG problem.

I’d recommend that you talk to your vet, get her spayed and consider seeing a behaviorist and doing obedience training. Your puppy needs to understand that YOU are the pack leader.
