Jeanne, I think this is a question you need to ask your vet; the dosage should be on the bottle of pills, or on an instruction sheet your vet may have given you. Is it being used to treat giardia or another parasitic infection? The dosage is going to be based on the dogs age, weight, and medical condition ; I don't think anyone here, even if they were a veterinarian, would be comfortable giving you Rx instructions.
Okay, thanks, The directions are on the bottle but I can recall the vet said something different and I can't call because the office is closed. I just took a chance on here to see if anyone knows. Thanks for replying.
