Suki, even with domestic dogs, they naturally do not need to eat every day. I've heard it is very healthy for them to be fasted 1 day a week, with just some tidbits... I fast Gonzo every so often, and he does not seem to care at all. If I give him a whole chicken, for instance, I will fast him the next day and maybe give him egg or pureed veggies and he does great with that. It is very natural for them to eat a big meal and go 1-2 days without food, because they still do have the same digestive system of wild dogs & wolves. Just like fasting every so often is good for people, even! Basically what Jordan said.

Gonzo got lamb Farmore for breakfast, and pureed veggies/brown rice for dinner. I thawed out half of a chicken for him tomorrow.

Fozzie got lamb Farmore for breakfast, then 2 meals of CN with veggies.

And they both just got a big slice of cantaloupe. They love it! It's really cute to watch them both get every bit of fruit from the peel part... Fozzie is now chewing on the peel, as well
