Puppy biting problem
We recently got a new puppy from a rescue centre, he is a German Sheperd Dog crossed with a Belgian Sheperd Dog, he is currently 8-12 weeks old, we arent sure because the vet said he was 12 weeks old, but the Battersea rescue home said he was 9 weeks when we first got him. He is currently teething and bits everything, including people, but he seems to be biting harder and harder. He even went for my nose when I went down to stroke him. Saying no doesn't work, and when I point my finger at him and say no, he just tries to bit my finger off.
Anyone got any idea?
