I have 2 dogs, 20 kg and 40kg, and 2 indoor cats. I bought 4 boxes size/animal specific frontline plus to treat all of pets. Cost me a fortune and see absolutely no effect on fleas! The ticks on my dogs did die, but still find live fleas on all my pets after 24 hours and 3 weeks. I ended up bought a flea comb to combat the fleas and used insect bomb to treat the environment.

This is the first time I bought this product, was previously using some local product. Seems it worked and can't find Cathy reacted negatively to the application. Wish to continue seeing the results.

I brought frontline plus for my dog. 8-17-18. He goes to pet smart every 3 weeks for a bath and the girl called and said he have fleas bad. I said no he uses frontline plus. She told me its not working. Got him home a couple of days later I saw fleas like crazy! Upset at this point I spent 47.00 for this mess and it don't work. I want a refund and he is due for another dose on 9-17-18. I have to now have my yard and house treated. I truly got it because dogs were coming in my yard and he is a house dog. I would not recommend this product to anyone. A total rip off!

We have used Frontline Plus for many years and had always found it to be good.... however.... in recent times the product doesn't work! No idea why. Where our dogs were flea free for years, all of a sudden they have them all the time (even there a couple of days after they are done!). Will be changing products and are now considering Nexgard Spectra. The money we pay for these products they need to work!
