Hi, i am going to take him to puppy class but he's only had his 1st inj today so as soon as he can go out we'l be there. spoke to the vet about his behaviour today and she said i should hold him firm when he's wriggling and squirming to get down and tell him "NO" she said if i put him down he's getting away with doing as he wants and i should show him who's boss, thats all very well but when i tried that he bit my nose! He looks so innocent but he's a devil.
