    • Impressed by Fast-Acting Flea Solution
Style: 2-25 lbs Size: 12 Count
So far, I have really enjoyed this flea treatment. The 12 doses are super handy and it's incredibly effective. Fast-acting as promised, it starts killing fleas in just 30 minutes. Easy to use, it's a blessing for small dogs and even safe for puppies. The best part is watching the fleas just fall off my pet. It also treats reinfestations, which is great. And the fact that no prescription is needed makes it even better. Highly recommended! ... show more

    • Essential for any rescue or household with pets
Style: 2-25 lbs Size: 6 Count
Capstar is a little pricey, but it is a lifesaver. I have a small rescue and I keep this in my rescue supply kit. When I pick up a new rescue, if I'm unsure about the presence of fleas, I immediately give one of these. It starts working within the hour and mitigates infestations.

    • NOT Fast Acting, and Do Not Die.
Style: 2-25 lbs Size: 6 Count
The media could not be loaded. Results were a surprising, because I only ever saw one or two fleas on my dog at any given time. I gave my 12 pound Pomeranian a pill around 8:00 p.m. About two hours after giving it to him, fleas were evacuating my dog in record numbers. Probably 70 or so in total if I’m being accurate. Really shocking in all honesty. That said, none of them were dead. They were all just moving around all over the bed looking like they weren’t well, but it’s now 2:00 a.m. in the morning and this is still the case. Over 6 hours after ingestion and they’re not dead. If anything they seem to be merely wounded or somehow intoxicated as none of them can jump. They just sort of move around in messed up circles. Not wishing to have them suffer, I picked each of them up one by one, all 70 or so of them and dropped them into some soap. That killed them within seconds. Not sure what this pill does, but fast acting and death isn’t AT ALL what happens. They vacate your animal and stay right where your pet was when they left and move in odd lines or circles for hours on end. Per the video, even the one not crawling around still had its legs moving, over six hours after my dog had eaten the pill. Very strange, and very deceptive description. In closing, this does not work within 30 minutes as advertised. It was closer to two hours before I saw the fleas crawling off him. It also does not kill as it claims to. They eventually leave, but they do not die. They just suffer until someone or something puts them out of their misery. ... show more

    • Didn't work at all for Alaskan Malamutes
Style: Over 25 lbs Size: 6 Count
Review Image by Kimberly W. Kimberly W.
First, let me point out that CapStar is NOT a preventative! It is supposed to kill adult fleas on the dog but it doesn't prevent them from getting fleas again - not does it kill anything but adult fleas, which means you still need something (monthly topical or oral flea medicine) to kill the eggs and the larvae or those will obviously mature into adults and you and your pet are stuck in the vicious cycle. That being said, here is my first and only experience with CapStar. We have never had flea issues until this year. I have two Alaskan Malamutes - one 105 pound "short hair" and one 110 pound long hair. Clearly, they both have the Malamute thick double coat. We usually like K9 Advantix II for flea treatment/prevention. Early this summer, I bought the Amazon brand that has the same ingredients. As K9 Advantix Ii. It arrived with no expiration date and I'm not sure if that's the reason that it doesn't seem to work, that it's not the same formula or perhaps the fleas have become resistant... or it's just an especially overwhelming year for fleas. Either way, I thought by trying this first and THEN putting their prevention on within a day or two would work. I gave them each a CapStar pill, nervously watched for adverse reactions and thanked God they didn't seem to have any issues. It also didn't seem to help the flea situation - they continued scratching and biting as before. Because I didn't want to give them back to back, I waited for about 48 hours before giving another CapStar to each of them. Once again, no reaction but the scratching and chewing hasn't subsided at all nine hours later. In fact, I almost feel like both times, they are actually scratching more after the CapStar tablets?? It makes me wonder if it is actually not killing the fleas but just irritating them and making them more active and angry (or at least more hungry LOL). I really needed this to work and was hoping that in conjunction with a topical preventative, we would be able to both kill AND prevent reinfstation with a two prong attack. Sadly, we are just out more money, time and effort. I should mention that a long side this effort, I treated the bedrooms that have carpet (the rest of the house has hard floors and we have a no-knap, outdoor rug I'm the living room because it can be power washed) Anyway, I sprayed the Vet's Best Flea & Tick Home Spray on the carpet, mattresses and washed bedding & blankets. It's difficult to get every possible location that a flea could be hiding but I was fortunate to be able to see a flea and spray directly on it. The Vet's Best spray killed it in less than 10 seconds. It does say that you can apply it to your dog's coat and rub it in down to their skin. That sounded too unrealistic with their thick coats but because it is natural, smells really nice IMO and obviously works, I think I will still attempt that on most of their cost/body, add Diatomaceous Earth to the floors, dog beds, rugs, etc and THEN try reapplying topical prevention. I just have to decide of I am going to use some of the 8 tubes I have left of the Amazon brand or try something else - might pick up the Frontline Plus that's on sale at Costco tomorrow. ... show more
