Hello! We have a lovely 11 week old puppy was on purina dry mixed with nature diet wet. We successfully switched to fish 4 dogs dry and are now swapping the wet (he eats such tiny amounts we were throwing away half the nature diet trays). We decided on James wellbeloved. We switched out a 1/4 of the nature diet with a 1/4 of the jwb amount for breakfast and a few hours later he vomited. Just once, just a little bit. Then for lunch we did the same and he threw up again a bit more. Shall I stop now or shall I keep going? It's only 4g of jwb per meal! Not sure. Any advice would be helpful and an alternative?
