Have you tried feeding a quality dry food such as Iams or Purina? The more expensive dry foods are meat based, which means that meat is the main ingredient. Alpha is, I believe, cereal based. You can mix a bit of tinned food in to soaked dry food, which will give it the flavour the pup is used to. Then gradually reduce the amount of tinned food. How old is the pup anyway?the pup is 9 weeks there abouts ,he is heavy saluki based so I was expecting a picky pup
