vomitting and diarhea is not really an allerg thing as my yorkie dd has horrible allergies and does not have this
sounds like intestinal upset -ibd or colitis situation. Best not to feed any fatty foods to yorkies as prone to pancreatitis and having a dog almost die of this it is real scary so please be careful - a little organic chicken, veggies like steamed green beans and steamed carrots ok but beyond that i would caution you to be real careful especially if you are seeing digestive upset. Innova is not a good food for allergies as it has too many ingredients so if she is itching alot i would get on a allergy limited ingredient food as that may help
