My not quite 12 year old Shih Tzu’s health suddenly went down hill after a 2nd oral dose of the flea medicine, Comfortis (She was 10 pounds and was prescribed dosage for dogs 10-20 pounds.) She began to feel bad 6 days after the 2nd monthly dose and began to skip meals and started losing weigh. tI took her to the vet 11 days after the 2nd dose because she wasn’t thriving. The Vet gave her diuretics and antibiotic. It seemed to help for 2-3 days, then she started downhill, but I continued given the meds. I took my fur baby back to the Vet 11 days after, the previous visit and he did X-rays and bloodwork. It took 3 days to tell me she had a high white blood count. The X-ray was showing something but it would take an MRI to know what. Three days after her 2nd Vet visit, I spoke with him on the phone, and he prescribed another, very strong antibiotic and said that I should call the manufacture of Comfortis. I did call them that day, Monday. In the early hours of Wednesday she died suddenly. I was shocked! The vet didn’t expect it. The manufacturer of Comfortis offered to pay for a Necropsy, which I naively thought was a test to see if their drug killed her. It wasn’t. I knew this only after the results came in and she had been cremated. The “necropsy” only showed the failing that she died from peritonitis and had low kidney function. Now I have no recourse to prove their drug killed my once lively dog. My Vet said he believes the Comfortis oral flea medicine was toxic to her.
She had a good three years left. I had her mother and she lived 15 1/2 years.
