Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

EFFIPRO Plus is for convenient, quick acting, long-lasting, effective control of fleas, flea eggs, flea larva, ticks, and chewing lice. EFFITIX Plus is for convenient, quick-acting, long-lasting, effective control of fleas, flea eggs, flea pupae, flea larvae, ticks, mosquitoes, and lice.

Is there anyway to dry this faster? Maybe with a hairdryer on low? Just letting it air dry with my dog’s short hair takes so long it just rubs off on everything
Answer by ChewyJan 04, 2022
If you are having a hard time getting the solution to dry on your dog, you should spread out the product when you apply it. First, start between their shoulder blades, then go down your dog’s back near the top of their sacrum, now you will want to fill in the spots between their shoulder blades and their sacrum. You could also try using smaller drops if needed.

Can you apply this same day as giving a bath
Answer by ChewyMay 20, 2020
After application, it's recommended to wait at least 48 hours before bathing your pet, with a non-stripping shampoo.

Is this an application or chewable
Answer by ChewySep 27, 2018
This solution is applied topically.

My German Shepherd is still scratching. He’s a big boy and it’s had to find a product that covers a 125lb dog. I will give this a few more days to see if it works better.

Cheaper price compared to vet!

I started using this when I found out one of my dogs had epilepsy and we could no longer use Trifexis for heart worms and fleas. I love that it’s the only medicine on the market that kills mosquitoes!

Works Great, Great Price

This product has worked just as effectively as the pricier brands. My vet recommended it to me, and it was a lot better for my budget when we had a multiple dog household.

Great stuff

I have a 50 breed black lab blue healer mix great dog, but he has sensitive skin. I would like to use the new long lasting collar but tried that 2 days later his skin was a mess from neck to shoulders. Anyway went back to drops used several decided Front line work best, then it quit working the fleas came back in 2 weeks. So again I starting reading reviews. Found this new product and it works great for him and the neighborhood Pitt I doggie day care for great thing
