Changing Dog Foods !

Because Sapphire has been sick, until I get a final diagnosis, hopefully after another test April 7th, the vet suggested changing dog foods. Because I prefer both dogs getting the same food, Lucky gets to change too. I am gradually adding the new food (and taking out the old food) from their twice daily feedings. As of today, have progressed to half of the old food and half of the new food. They have both come to the realization that the new food is MUCH better than the old food. Sapphire eats all the new food out of her bowl, then eats the old food. Lucky, on the other hand, eats all the new food and then just walks away. If by some accident he gets a piece of the old food in his mouth, he spits it out beside his bowl.
