Hello I have a question on the heartworm medicine. I have a min. schnauzer 9 months old. She weighs 10 lb. 2 oz. She will be small because mother was 11 lbs. and father 13lbs. My vet gives Trifexis for heartworm prevention. When she weighed in over 10 lbs he bumped her dose up for dogs that weigh 10.1 to 20lbs. That made the meds go from 140 mg to 270 mg. per dose. So last month I split the pill and just gave her 1/2 . I am uneasy doubling the dose when she only weighs 10.2. I will give her the other 1/2 next month. I am not sure about giving her that large of dose because she is still so small. I live in South Carolina and she is inside dog, goes for 2 walks a day and potty breaks only. Of course I don’t want her to get heartworms, but I also don’t want to pump her little body full of this stuff, month after month, if the smaller dose will do the job. I think Trifexis is new and not sure about long term side effects.
