I posted earlier, but it disappeared...
Last month about 12 hrs after I gave out heart worm one of my dogs had severe diarrhea. When cleaning it up, I found her heart guard undigested in the mess.
This month, about 8 hours after dosing, she had diarrhea again. My doc agrees this is not a coincidence. She is five years old, has been on heartworm prevention, interceptor or heartguard, her whole life. Heartguard since interceptor was taken off the market. Has anyone else had such an experience? Since all the medications have the same active ingredients, we are a bit stumped. Wondering if it is the beef chewie delivery that is the problem?
