Also, the mosquitoes seemed less interested in him, which was a big relief during summer evenings. The monthly protection gave me peace of mind without having to worry about reapplying too often.

Safety and Side Effects

I was initially concerned about side effects, but my dog didn’t experience any irritation or unusual behavior.
