This post has nothing to do with dishes, but everything to do with pets. We recently moved and changed vets. As a result my dogs were put on Comfortis for fleas. They have been on Sentinel for years with no problems and no fleas.
My 3.5 year old got very, very sick. $400.00 and a sleepless night later it appears it was the Comfortis that made her sick. She got fluids, an Xray and stomach medication and will be OK. Not the way I wanted to spend one of my rare free days!
Be very careful with this medication. It is relatively new I understand and it touted as a miracle drug.
My other two did not appear to have any issues with it. But, I won't use it. I have been attempting to locate the company to report the problem.
