Hi, I have 9 week old border terrier who in many ways is beautiful, she’s practically toilet trained, sleeps in her crate for 10 hours at night with one quick toilet break. We have a big problem with her becoming over excited and biting our hands arms legs and clothing and growling. She’s is ripping clothes. We tried the stop sit treat approach which worked so well that she decided to bite and as soon as we said stop she was already sat waiting for reward. We can’t walk across the garden without her pinned to our ankles. In the house she does the same, we tried leaving the room only to find her whizzing room. Only for her to head straight for us and start again on our return. I was wondering about using a crate for time out but didn’t want to upset her bed time routine. Has anyone got any advice.
