Need Food Help

[Dobiegirl24]

I posted awhile ago that Pepper was underweight, well he still is and just keeps loosing weight so we took him to the vet today. The vet said he is in great health, except for his weight, in the last 3 months he has lost ten pounds. We brought in a stool sample but they only found a few roundworms, not enough to account for how much he has lost(but she did give us a dewormer to get rid of the ones he has). The vet recommened that we switch him a a performnce or puppy food. She recomended Eukanuba. There is NO way I would ever feed him Eukanuba, so I need recomendations for performance or puppy foods. He is on Canidae now, and I would keep him on that but it is an all life stages formula and they have no performance formula
