True, you have to find the right amount of meat to serve for the breed, size, age, activity level, etc. They were all adults, I might add. I would not feed a growing puppy or special needs situation a raw diet.
We used to know someone who fed her tiny doxy raw meat but she over fed and that poor little thing was grotesquely overweight. Our dogs would skip meals as they just didn't need to consume heaps of meat every day.
We now feed kibble due to budget and time constraints. They get extras from what we eat, depending on what that is, i.e. tuna, eggs, fruit, etc. No pasta or sweets ever.
