If it is cushings the meds can be causing the diarrhea. Cushings is when the body produces to much cortisone, humans get it too. It's the cortisone mixing with meds that causes the problems, well for Tonee anyway. It was like mixing bleach and ammonia together and it blew up her gut. Thats how the emergency described it to us. After the new Dr., a specialist , got her on the meds, she had to have blood work every 60 days, at $222.00 a pop. And then all her meds. She had more than one problem going on. I spent thousands on her in her lst 3 years. Not a cheap dog !!! Money well spent though. I would have spent all I had to make her better. She also had horners syndrome. $85.00 just for the 'office visit' every 90 days, and meds for that too. Bought all her meds at a drug store, nothing from the vets. Gotta love those cockers
You'll feel better once you get the tests done. And maybe the vet will rule out cushings right away for his own reasons. But better to get it checked. They can live with cushings, Tonee was proof of that !!
Please keep me posted and we will pray that Max gets fixed up right away.
