Hello, I am a new owner of an 8 week old Cavapoo named Ozzy. He is adorable and so so loving. He is going through the night in his crate and uses it as his safety net during the day. Potty training is happening slowly but when we take him out in the garden he is fascinated with biting our ankle and trousers. Wherever we walk rub he is right thereZ Any tips/advice on what to do? Also any tip on getting him used to a collar?
