Provecta 4 Doses Advanced for Dogs, X-Large/Over 55 lb

Works great. The dogs had fleas on them and I applied it as directed and it killed the fleas and stopped more from getting on them. Been using this product for years and always have had great results.

I used to use Frontline, but that stopped working (seems like the fleas became immune to it). This one seems to work quite well. It goes on pretty easy though I have found that it seems to work a little better and faster if it's spread out in various spots along the neck and back and not all placed in one spot. Spreading it out also kept more on them as both my dogs did a full body shake after putting it on and, the first time when I put it all in one spot, some of it flew off when they did this, but not when I spread it out. It does have a smell, which I'm sure can't be avoided, but it doesn't seem quite as bad as some others I have used and it doesn't seem to bother my dogs. It's important to note that this is not formulated to keep ticks away and it definitely doesn't. It does take about 12-24 hours for it to spread all over the dogs and start to work with the initial application. I still see fleas, but they are always sick (walking around in circles, barely moving). It seems to take a little longer to kill them than what I've used in the past, but it does kill them. It also seemed to last ALMOST the full 30 days, but did seem to start to weaken a few days sooner than the 30 days. Do note, this CANNOT BE USED ON CATS and is LETHAL TO CATS, so this is not one that you can use on all of your pets. Overall, I'm happy with this product and I will continue to purchase as long as it continues to work.

I've tried some of the other brands and they caused skin irritation. This product does not do that and it works great.

Been using this for a few years now, works well for the price.

It works really good there hasn’t been one flea on my son’s dog great product 5⭐️
