Success! I went to Pets at Home but they didn't have a freezer so no tripe, also they only had NatureDiet in Lite or Puppy. But then I went to Jolleys where they had a freezer with tripe and also NatureDiet Lamb and Carrots and Rice, so I've got 8 of those and gave him half a pack for his second lunch which he wolfed down - he had his Burns lunch just before I went shopping. Should I give him one whole pack of Naturediet for one of his meals, one meal of Burns and one of tripe? All with pasta and/or carrots etc added? I bought two blocks of the minced tripe and chicken to try him with - I shied away from minced tripe on its own because it said on the pack for working dogs only, do not feed to pets! Does this matter?
Now I'm going to go on tesco.com to add lamb breast to my order! I will fatten this boy up! But don't worry, I'm adding it in gradually. He's very happy up to now! Loved the Naturediet food.
Thanks everyone, I'll keep you posted.
