LYN, HOPE SHE'S BETTER TODAY! ONE OF THE THINGS WE DO WHEN WE SUSPECT ULCERS, SINCE THE GASTROGUARD TAKES 3-5 DAYS TO BEGIN HEALING AND THEY ARE OUCHIE! IS TO SQUIRT SOME BARIUM..YEP GOOD OLD CHALKY BARIUM ! IT COATS THE TUMMY AND ULCERS, BLOCKING THE PAIN WHEN THEY DO EAT AND FOR THE TIME IT TAKES THE ULCER MED TO BEGIN HEALING IT, WE PREVENT THEM FROM GOING OFF THEIR FEED...OUR ONE VETS PRIMARY INTEREST IN VET SCHOOL WAS EQUINE ULCERS AND I'M SURE THIS PRODUCT HAS SAVED SEVERAL OF OURS IN THE LAST 2 YEARS! ANY SMALL ANIMAL VET THAT DOES CONTRAST X RAYS SHOULD BE ABLE TO GET IT IF THEY DON'T STOCK IT, CHEAP INSURANCE!! ~HUGS~ TO YOU AND TO FANCY!
