Can rats eat dog food?

Yes, but only a little: rats can eat dog food. Germany’s Veterinary Association for Animal Welfare (TVT) names dry dog food for the small share of animal protein. Blue Cross mentions dry dog food as a protein source. Woodgreen includes fish-based dog kibble with no meat or animal derivatives and at least 20–25% protein in its homemade food mix. The Merck Veterinary Manual and the RSPCA suggest hard or low-calorie dog biscuits for gnawing. Woodgreen lists wet cat food, meat in jelly or gravy, among healthy treats to feed in moderation and as a way to help give rats their medicine. As the main food, though, RSPCA Australia recommends food designed specifically for rats rather than pellets for rabbits, guinea pigs or other animals.
