Vegetables for dogs

Question
Hello, I have a dog with anal gland issues. I have been reading that fiber can help with these problems. What vegetables could I feed my dog to help with his fiber? I feed him Eukanuba Lamb and Rice and I want to add some fresh vegies, any ideas? Is there a good website to go to to research this?

Answer
Mostly depends on what the 'issues' are. Pumpkin (canned) is the vegetable of choice for fiber issues. Other ones add very little. Vetasyl caps help also. Those are available through the vet's office OTC.

I don't know of any web sites for this- just do a google search.
