Is it ok to continue giving the heartworm med on a girl in whelp? I am using the liquid cattle ivomec on the food.

I don't.

Ask you vet....however, my vet insists I keep them on. I haven't had a single problem.

My vet mixes it with propylene glycol and I give it even during pregnancy/ dosed like Heartguard. No problems

Thank you.

I don't either.
