Peanut is in the chewing stage. Well last night she was biting me hard. She was growling as she was doing it and the more I said no, the angrier she got. I gave her time out in her crate, which by the way I don't crate her, I put her in a pin since we are gone most of the day. But I wanted to let her know she was being punished so I put her in her crate. She was howling and barking and crying and whining like you won't believe. Is this normal??? Also, is the biting and growling normal? She is 3 months old.
