I would really rather just do revolution when he could be exposed to fleas or mosquitoes. He's never going to be exposed to ticks. Around here it's only during the summer that I'll have to deal with mosquitoes and doubtfully fleas. If I use a topical it will have to be compatible with a rabbit. I've been using simparica trio. I hate it because it's oral. What do my friends here think? So I guess my question is should I prevent heartworm year round or just when Mr Fre could be exposed to mosquitoes. He's a total house dog and doesn't have to be outside ever unless it's a beautiful day. He has his very own toy let ![Pile of poo :poop: 💩](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f4a9.png)
