Greetings from 2 and a half year old Molly, we live near Oxford in the UK. She was a very persistent biter as a young pup, nothing deterred her. She grew out of it at about 18 weeks. I would trust her mouth anywhere now. It is a real pain when they are in the Crocopup stage, but it is a very necessary stage. It is how they learn to control their powerful jaws, an essential skill for later life. Kongs are magic. At one stage i had 10 in use. Treat ball and Buster cubes are also a great idea, make them work for their food.
Some, not loads! I have a moderately large freezer. Top drawer is things like peas, fish and meat. Middle (largest) drawer is kongs, meat and homemade treats for the dogs. Bottom drawer is meat for the ferrets and ice, plus any pre-prepared boxes of food for DH's lunches
