Both of mine are on Trifexis. I give them half of the medication on the first day of the month and the other half on the second day. Now I'm worried. Piper has been on it for at least 3 years. Jilly has been on it at least a year. Must see my vet. They could not tolerate the whole dosage. My vet said to give one half on first day of month then second half. They have not thrown up since. Piper weighs six pounds and Jilly is five. |
