We have (3) different breeds of fur-babies but we feed them all 4Health from Tractor Supply. It is supposed to be comparable to Taste of the Wild. We also add fresh cooked beef, chicken, fish or liver to their feeding once a day, as well as cooked eggs. We add coconut oil, GSE and Nutri-Cal (for puppies and pregnant or nursing mommies only). We have had great success using these products and feeding this food. We tried Blue in the beginning but caused serious diarrhea. We tried various other brands and there were additives or manufacturing facility issues that steered us away from them. They've been on this kibble for over a year now. We have a lot of fur-babies and through research found that this is the best dry kibble for our babies and for us. No digestion issues or major health concerns (yet....touch wood).
We are back to where we started with Nature's Recipe, canned. It's not the highest quality but it is the only one his stomach seems to tolerate (ie: no diarrhea). I'm not sure how you feel about homeopathic remedies but we also started Oliver on an all-natural (approved by our vet) Digestive capsule. It has ingredients like Marshmallow bark and Slippery Elm which coats the esophagus and stomach. (these are the same ingredients in Throat Coat tea which is awesome for humans when you have a sore throat!) He gets one with breakfast and one with dinner. We open the capsule and put it right into his food. He also gets one regular-strength Pepcid at bedtime. He no longer regurgitates!!!!! (he still vomits a little when excited) The down-side is he has gained some weight from keeping his food down. LOL!
Life is always an Adventure with Oliver!
