My little 1yo girl was recently spayed and she went from 3.7lbs to 4.4lbs. Mind you it's winter and we are walking a bit less than when the days were nicer outside. The vet suggested Royal Canin Neutered Food. She hates it but loves the regular Yorkshire Royal Canin. What your guys' and gals' opinion on just feeding regular dry food mixed in with some veggies/meat and exercising her more for weight control?
