My dog had a bug, but I lost it. What if it was a flea or tick?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 11 lbs

I saw a very small dark bug on my dog's fur. I panicked and kept trying to grab it, thinking it could've been a tick, but then lost it and couldn't find it. We checked for 30 minutes and couldn't find anything in his fur. I got very nervous that it was a flea, so I sprayed frontline. I had sprayed frontline on his back about a week ago, but had realized I didn't do it right - not enough sprays and not other parts of body, so I just try to spray other parts. Is there something else I should do?

I wouldn't recommend anything else specific as long as you don't see any other bugs. If you see more or if you look at the base of Cosmo's tail and along his back and see little black flecks of dirt in his fur that could be flea dirt (the feces that fleas leave behind) then I'd recommend talking to your vet about a different flea preventative. In some areas there is resistance to topical flea medication.
