Hi, I have a 12 week old that I got when she was 8 weeks old & I can’t imagine life w/o her. She is so sweet but she is very wild. Between myself & my husband we have had 6 puppies but she is not like any other. She doesn’t get potty training only about half the time. She bites on your feet and any body part she can get continuously and draws blood. She gets into anything & everything. Doesn’t listen. Eats on the furniture, attack’s my cat and other dog. Is this normal for the breed ? Any training advice, tips? Please & Thank you ?
