How much protein should a Chihuahua puppy have in his/her dry food, especially if they are on the small side? The breeder was feeding her some type of off brand food called PRIDE dog food and I have never heard of that brand in my life. They also told me to only feed her food that had 22% protein in it but that sees kind of low to me, am I wrong? I want to get her started on the Diamond Naturals but don't know if the protein % is too high. She turned 7 weeks old on Tuesday of this week.
