No birthday's here, but we baked this for a treat to add with their dinner. Smells yummy and the dogs love it! My only critism is it requires a cup of oil, which seems like a lot so we only feed it every other day! It doesn't seem to upset their tummys though, we give about 2 spoonfuls. It makes a very good amount to, I have 3 large dogs and a week later and we're only a little over halfway through it.
