I have a red tri Aussie that is almost two years old. My vet gave her a two month supply of Comtortis for flea/ticks. It's been a terrible year for both. She is a inside dog. We do live in KY, where problem is bad for these. Would like advice before giving any more to her.
I read this website alot, to learn all information I can on safety and health issues for Aussies.
