Frontline doesn't need to be given every month unless you have an active flea infestation. It's good for up to 90 days (see label on box.) Most apply every other month during flea season.

I live in snowy cold maine and I use it very 30 days..Fleas live inside in your rugs..

we do it too, in the summer months when fleas can be a problem. Saves a ton of money. I just share one tube for 100+ lb dog between our two 50# dogs.

It's a good tip to pass along!

You can do the same with cats. Get the largest package available and then pull up .8 on a 1cc syringe. Make sure you don't use the enhanced Frontline. Compare the labels to ensure you are getting the same ingredients in the cat and dog forumula so you don't kill the cats.

I tried the syringe once Hiw, and was fumble fingers with it. So, far, marking the package has worked better for me.

What is enhanced Frontline?

please do not put frontline plus on cats. Only do that wit frontline. NO PLUS ON CAtS!!! EVER!
