Hello Kate, I can relate to Labradors, I love my food too...anyway, I find my young lab piles on the weight when I give her a bit more than she suppose to have, she is young and gets loads of excercise but she needs very little food to keep her healthy. I have had three labs before and as you know, they are very food focused, I am lucky that my dogs have a room where there is nothing else foodwise to get at...that is what I need, my daughter had a very overwieght lab and she changed her firstly into a rake of a dog, a bit like a greyhound, but now she is beautiful, all due to keeping her from food and on a very limited diet but loads of excercise...yes, I know, that is exactly what I need, you have at least given me inspiration for myself, Sandy (was a Lab in my past life)
