Help!!!!

[Kizzys Mom]

I do think they get tired of the same stuff everyday. Kizzy had always eaten good till a while back and I changed her dog food. then she was eating that good until the last 4 or 5 days. Usually cleaning her bowl every morning and evening. Then she just took the last 4 or 5 days walking to it, sniffing it and leaving it. But he energy was about the same and she didnt seem sick at all but she also wasnt drinking quiet as much. But usually by late evening she finally eats it. So she didnt have much food left and I bought her a new flavor in the same kind over the weekend and this morning when she wouldnt eat the old, I poured it back into the bag and opened the new, gave her that and she ate it like she was starving this morning and this evening. So now i've got some of 3 kinds and I'll just switch em. when she seems not to eat one, i'll try the other kind. Maybe she just likes a change. But I tried the cottage cheese when she was lots younger, like 3 months old. I mixed about a half to one teaspoon level into her food, at the time I was giving her hard food but moistened to make it softer. That evening she had diahrea so I have never given her that anymore. I also gave her a few bites of cheese, about a third of a slice total, one day and later that day she threw up a lots. So not sure if she has a problem with dairy stuff or not. I do have lactose intolerance myself. Goodluck with your puppy. hope they keep eating good for you.
