Specifically, Cutter brand insect repellent - if I can use a DEET product on a dog, I’d prefer Cutter because it does not leave greasy residue.
I’m asking because the mosquitoes and gnats will NOT leave my dogs’ heads alone! They shake, shake, shake their heads constantly while we’re out on walks. It can’t be much fun for them, not to mention I’d rather not end up with aural hematomas.
*Of course I wouldn’t spray directly on their heads - into my palms and then rub into fur and on ears.
