My dog won't eat Blue Buffalo, only Iams. Is Iams healthy enough?

Updated on September 23rd, 2025

I have a 9 year old Chihuahua/terrier mix. We have been feeding her Iams her whole life but I recently saw an ad claiming that Blue has healthier ingredients. When comparing ingredient labels it does appear that Blue is healthier. so I tried mixing the 2 in my dog's food - she literally separates the two and only eats the Iams! should I keep encouraging Blue or stick with Iams?

Iams is perfectly healthy dog food! The ingredients in Blue Buffalo may appear different, but both diets are balanced in their nutrients and can provide an excellent diet for any dog. It sounds like your dog likes the Iams, so I see no reason to switch to something that could upset the balance.
