Frontline plus blue 23-44lb med 3pk

My go to for our dogs. No fleas or ticks here. Simple to use and apply.

Works as it should it’s great for fleas and ticks especially if you live in wooded or rural areas

This is a well-known and trusted flea & tick treatment that’s easy to use and works as part of a monthly routine. Each application provides about 30 days of protection, and the formula is designed to kill adult fleas, eggs, larvae, ticks, and even chewing lice. Application is simple—just apply it to the back of your dog’s neck, and it spreads through the oils in the skin for full-body protection. It’s also waterproof after drying, which is helpful for active dogs. In terms of performance, it works well for many dogs and can kill adult fleas within about 12 hours and ticks within 48 hours, helping break the flea life cycle. On the downside, effectiveness can vary depending on your area—some users report it’s not as strong as it used to be, especially in high-flea regions. It can also take a full day or so to start working, and you’ll need to stay consistent with monthly use.

Seems to be working. She has no fleas or ticks. I'm happy with the product

Didn't work. I have bought front line for years for my dogs and it's always done me good in the past. This batch didn't. This time when I applied it, it didnt do anything and i ended up with the worst fleas I've ever had. I decided to wait a few days, I know in some cases it takes time for the medication to work. After a few days I couldn't take it anymore, the fleas were out of control. Had to pull the combination of dawn dish soap and coconut oil out to get rid of them. Normally you would buy this stuff as a deterrent or treatment but I felt like it attracted them. Now I'm wondering if I should hope that I got a bad box or maybe it's time to switch to a different flea deterrent..
