ok i have been switching sarah over to nvi first the rabbit yes geez thats before i knew any better anyways it took bout 2 weeks as i had some old food left. well i have been seeing some reactions and i thought it was the rabbit so i switched her to salmon. well last night she had the same type of stuff. shes been having red dots on her tummy and her chin gets red and then her beside her nose got red so i think ok the pollen worse as my other dogs are having the same trouble so i give her antihistamine and she gets better. now this morning she threw up. all of her food it looks like. she has thrown up before in the summer but its usually just she heaves and nothing comes out this am she threw up her whole breakfast it looks like. she seems ok now but my q is do i stop the food or just cut it back maybe. i was thinking maybe i just need to put her on a limited ingredient diet like wellness simple solutions or natural balance lamb and rice. not grain free cause they have potatoes and she has a yeast problem also. any help would be appreciated. how bout canine caviar has anyone heard of this?
