My husband put sentry flea and tick squeeze on our dog 2 days ago,and it didn;t work on the fleas. Can i put frontline plus on him today or do i need to wait?


Online vet, Dr. Marie

Dr. Marie replied:

Hi and thanks for your question. I get so frustrated with over the counter flea products as they rarely work.

The frontline really should work well for you.

There really should not be a problem with applying Frontline now. Just to be safe, I would apply it in a slightly different area of the skin that you applied the Sentry.

Make sure you use it for at least 3 months in a row and make sure that all of the animals in the house are treated.

Hope that helps!

Dr. Marie
