Health & WellbeingMy large dog has diarrhea on grain-free chicken food. What next?
Natures recipe is a good brand but if he is still having issues you may want to talk to you vet about putting him on a prescription GI diet like science diet I/D or purina EN. If you are concerned he has food allergies, then I would stick with grain free but I would also look for a diet that doesn't have chicken like natural balance venison and sweet potatoes. A lot of dogs are allergic to chicken and beef. If you haven't had his stools check for parasites, campylobacter, and giardia, I would have your vet do that. It is not normal for them to have diarrhea so if it continues, I would certainly have it looked into. Your vet may want to do blood work and x-rays on top of the fecal. You may want to bring him a fecal sample as it is sometimes difficult to obtain a fecal sample when they are having diarrhea. Finally, you can also start him on a probiotic. I like purina fortiflora or propectalin paste. I hope this helps!
