Thankyou very muchWhen he first comes to you, it's best to keep him on the same food as his breeder was feeding, to reduce the number of changes in his life from all happening at once. Then, have a look at the ingredients. Do you really want to change it, or are the ingredients good quality?
So I should keep finding this to him for a year like the breeder told me?That looks like a decent food, it has clearly labelled ingredients with a good proportion of meat. If he does well on it, I'd probably keep feeding that brand, just changing onto the adult version once he is grown.
