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?
