wet food for a puppy, Taro's first 2 months

Taro is 2 months old and I try to decide wet or dry food, my friend says do both. I decide to start with mostly wet because he is still tiny and needs more water. So far he eats very well but his poop is soft, I think because I give too much at the start. My vet in Khlong Toei say reduce a little and go slow, puppy stomach is very sensitive. So I give less and mix in dry food slowly. Also the wet food is quite expensive, around 200 baht per day for him. I tried a cheaper brand but he did not like it. Dont buy too many cans at once, open ones go bad fast in this heat, I learned it the hard way with the first can. Next month I will try to switch to half and half, see how he goes.
