Do Chihuahuas need a breed-specific or small-breed formula?
Breed-specific food is not required, but many Chihuahuas benefit from small-breed or toy-breed formulas. These typically offer smaller kibble and a better calorie density for tiny mouths and fast metabolisms. But be sure the recipe is complete and balanced and you measure portions carefully.
How many calories should a Chihuahua eat each day, and do treats count?
As a reference point, a six-pound dog should receive about 225 calories per day, including treats. Because their daily budget is small, even a 50-calorie snack can account for roughly a quarter of a Chihuahua's total, so measure meals, track extras, and ask your veterinarian to help adjust the plan to your dog's weight, age, and activity level.
