Frontline worked for years. We applied it 10 days ago. It didn't work this time. Maybe due to the mild winter. Who knows? When in doubt, talk to your veterinarian. We did. She recommended Comfortis, a fast-acting oral medication. She also suggested that we vacuum thoroughly (for several days in a row) and wash everything the furkids had come in contact with - everything that will fit in the washing machine, that is. On it, doc.
Comfortis worked and it worked fast. What now? The vet recommended that we go back to Frontline next month - that most likely once our dogs are completely flea-free it will work again. And since Frontline gets rid of those pesky ticks, too, we'll give it a whirl. Check back in a month and we'll let you know how it's going.
