Frequently Asked Questions
How much should I feed my Chihuahua?
Adult Chihuahuas (2 - 6 lbs) should be fed according to the specific product's feeding guide. As a general guideline, divide the daily amount into two meals. Avoid free-feeding, as Chihuahuas can overeat if food is always available.
Is grain-free food safe for Chihuahuas?
The FDA investigated a potential link between grain-free diets high in legumes and dilated cardiomyopathy (DCM) in dogs. The research is ongoing and inconclusive. Unless your Chihuahua has a confirmed grain intolerance, a high-quality grain-inclusive food is generally recommended by most veterinarians.
When should I switch my Chihuahua from puppy to adult food?
Small breeds like Chihuahuas typically transition to adult food around 9–12 months. Small breeds mature faster than large breeds.
