Works Great
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.

Great flea medication works in 15 minutes
Was trying to find something that would not harm my pets and it would work very quick. Was recommended this. Let me tell you if you want to get rid of a flea infestation on an animal. These things are great. They work within 15 minutes within 24 hours all the fleas are gone your pet is happy and healthy fair warning some pets will get diarrhea from them not all but some I have 10 cats that I use these on two out of the 10 always get diarrhea when I get these pills to them like I said, they are great for getting rid of fleas fast and seem to be pretty harmless. Been using them for about eight months so far.

Good for small dogs
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.

Works for getting rid of fleas
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.

Great product!
If you’re in a bind, this is a great item! I have one little dog that just attracts fleas! I washed the dogs, put flea/ heartworm meds on and THEN found out you have to wait 2 days after a bath or the meds won’t work! Capstar to the rescue! Works like a charm, but EXPENSIVE!!

A definite must have!
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.

Works but can be a pricey if you need them long term
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.
