Thanks for your response - hopefully his teeth will soon sort themselves out. It is shame he is suffering because he is such a lovely lively little thing. I have one more question please. When I bought Oscar at 8 weeks old, the breeder was feeding him on tinned puppy food so I carried on. He loved it until about 3 weeks ago. I tried varous other tinned puppy food but he wasn't interested so I tried him on dried puppy food which he seemed to like. However, over the past few days, since he started teething, he has gone off this as well. He only picks at it now even if I moisten it. Can you recommend something for me to feed him on until he has finished teething. He is still very active and playful. He does eat a little but not as much as he has done. Than you
