If you’re looking for something that is a fast flea control and is an effective quality product. Then this is your go to. This is not a preventive, but this will help to kill fleas fast to get them off of your dog to help the itchiness and to keep your animal from being miserable, my dog took this two days and that’s all I needed and they were gone and she’s been fine since. this product is expensive, but it is very effective. You get what you pay for the value for the money. ... show more

    • Good for small dogs
Size: 6 Count Style: Small Dog 2-25 lbs
Review Image by Daniel Daniel
This definitely works and works fast. I gave this pill to my two year old pug, and within about 15 to 30 minutes you could clearly see the fleas reacting and coming off. It was honestly a huge relief to see how quickly it started working. My dog had really bad itching during the summer, and after finding out he had fleas, we tried a few things that did not help much. This pill made a noticeable difference almost immediately and gave him real relief. The tablet is very small and easy to give, especially if you hide it in food. For the price and how quickly it works, this is a great product to have on hand if your dog has fleas. I would definitely buy this again. ... show more

    • Works for getting rid of fleas
Size: 6 Count Style: Large Dog 25+ lbs
I give my dogs one of these prior to going to boarding and immediately when they arrive home after boarding. It does the trick! No more itchiness. My dogs are not usually exposed to situations where they could pick up fleas, so it's great for boarding and daycare. I don't like putting topical poisons on my dogs' fur because, well, poison. I also use Sentinel which prevents them from getting infested should they pick up a flea here or there, but the Capstar is fantastic when I know there is a good chance they were exposed. This only works for 24 hours, however, so if you want something longer-lasting, you'll likely need to go to your vet. I like Capstar because it is safe to give almost every dog. ... show more

    • Works but can be a pricey if you need them long term
Size: 6 Count Style: Small Dog 2-25 lbs
Works, kills fleas don't know about ticks my dogs didn't have those. Can be a pricey if you need them long term but for a very short period they work. Just keep in mind there are only I believe 6 pills in a box. I would have given an 5 star review if not for the price.

    • A definite must have!
Size: 6 Count Style: Small Dog 2-25 lbs
Highly recommend to kill fleas on the spot! I have a toy yorkie and this was safe for her size. There is no smell at all unlike some others that have a little smell. Once I put this on it was like clock work! With in the time frame of 30 mins these were falling off of her! She was no longer scratching or irritated at all. My pretty baby was able to sleep comfortably and relax. This is definitely worth the money as well not crazy at all in price at all. ... show more

    • Worked Fast and Gave My Dog Instant Relief!
Size: 6 Count Style: Small Dog 2-25 lbs
I’ve tried a lot of flea treatments over the years, but Capstar truly impressed me. Within half an hour, I could actually see the fleas dying off — no exaggeration. My little dog (about 18 lbs) had been scratching like crazy, and this tablet brought almost instant relief. What I love most is how easy it is to give. I just wrapped it in a little cheese, and she didn’t even notice. No messy topical creams, no lingering odor — just quick, clean results. I used it as a jump-start before following up with a long-term preventative, and it worked perfectly. If your pup is suffering and you need fast action, this is the one to grab. It’s a reliable, vet-recommended fix that actually does what it promises. Highly recommend keeping a box on hand — it’s a lifesaver during flea season! ... show more

    • The best I've found
Size: 6 Count Style: Large Dog 25+ lbs
The flea's were absolutely horrible this year! I tried mess everything and this product was worth the money that I spent. They fleas were gone for my dog by the next day after the first dose and I went ahead and gave her one more dose the next day just to make sure. It works wonders. I did not have to give her another dose until the next week so it does last a good long while. I do have to wrap it in a piece of cheese to get her to eat it but that's no big deal because it is easy to get her to take it. ... show more
