I'm about out of the purina one puppy Baxter's been on and am getting ready to switch him over to canidae. So I added just a little bit for the first time this morning. After he was finished he went over to his food container and acted like he wanted more. So I pulled out half a hand full of Purina and half a had full of Canidae put them both on the floor and told him to go at it. He smelled both and went and and gobbled up the canidae. Then when he only had a little left I mixed them to together on the floor and he sniffed the canidae out and ate it first. So I guess it's safe to say he's probably not going to have a problem with me switching his food! I sure hope it agrees with him cuz I know this if a better food for him. Any way just thought Id share!
