No Mate, if you are going to feed veg then it should be raw and pulped, in simple terms cooking the veg killes off a lot of the goodness, and dogs cannot digest whole veg.
the reason for the pulped veg is to replicate the veg in the gut content of prey animals, the recognised amount for dogs is said to be around 10%. some people feed it, others just feed meat, I like the more varied diet. Dr Billinghurst amongst others have several good books out on the subject.
Personally I do this.......
I mix minced meat and tripe, fruit/veg, a dash of cod liver oil and a bit of garlic puree, then
