Hi Steven, licking lips can mean he’s feeling sick, food intolerances can cause nausea sometimes…. try & find a diet that has just 1 protein & 1 carb, a protein that he hasn’t eaten before… there’s the “California Natural” Lamb & Rice with just 4 ingredients, its good to start with.. maybe with licking lips, stick with a diet where the fat isn’t too high around 10%-12% fat, if you need more info join this Face Book group Called “Dog Allergy International Group” look in the files there’s a heap of limited ingredient foods with their links, medicated shampoos, Salvia & Hair testing kits etc..
