My advice with dogs is not to chop and change their diets.

I like LANE have a rough collie. She is used to a particular flavour of Tesco's (turkey, lamb and green veg). In fact even another flavour of Tesco's and she is sick.

I don't know if it is the collie breed or all dogs. But I say, once you find something your dog likes - stick with it.

I suplement her diet with a boiled chicken wing. Also a bit of boiled veg or a bit of leftover people food.

Do remember that manafactured animal food is not always best. Although a dog won't come to any harm eating this food alone - she will be a lot happier and healthier with a bit of traditional food down her neck!
