If I was hunting with my dog I would do something.
I went with Bravecto because it does protect (yes tick bites but dies before it can release it's poison) against lyme carrying ticks, and I prefer to not have a greasy topical solution (permethrin) on my dog. My dog is a house dog and she often sleeps in my bed. There's no perfect solution but that is the one that works for me.
As for the next month or so I'll just try to keep her in non tick infested areas and check her after going out.
