Hey everyone..

So here is the background on our Bella..

We got her last week (from a client), when she was 8 weeks of age, and she was taken from her litter (by said client) at 6 weeks of age.

When I picked her up, she had fleas and roundworms, both of which were treated 20 minutes after I got her.

She's taken a liking to nipping both of us, and the vet said that it is best to hold her suspended for 30 seconds, and it doesn't seem to take. We've also tried ignoring her, and that works in calming her down, but she will still nip us after (including when we are petting her).

She also snarled at me today when I pushed her away from a meal that I was eating..

Suggestions?
