  • Easy to use oral tablet for large dogs
Love how this comes with 6 doses and is so easy to give my big dog. The oral tablet goes down quick and clean, no fuss at pill time. It fits perfectly for large dogs like mine and makes flea protection simple and reliable. I would definitely recommend to other big-dog owners.

  • No prescription needed
Love this for my dog. Easy to use oral tablet, so no messy dosing. It feels fast acting and actually works pretty quickly on fleas. No vet prescription needed, which saves me time and trips. Exactly what I needed.

  • Recommend product
First time using it and so far I am satisfied with the results. My 1yr 2month husky was filled with fleas and fleas eggs and with her coat was hard to see them. I gave one tablet to my husky and one to my senior pitbull and this stuff started working within 30 minutes no lie. I have added a picture of the fleas I was able to take out while brushing my husky. Adult and small fleas dead. I definitely with buy again & definitely recommend. ... show more

  • Easy to use oral tablet
Pretty solid overall. I like that it's an easy to use oral tablet, you can give it without a vet prescription, and there's no mess or rubbing off on fur. It would be better if it lasted longer and killed fleas faster, but it does the job most days. Not perfect, but solid.

  • Yes I recommend it.
Someone recommended it to me. I was doubtful. My Australian shepherd/ husky mix was going crazy biting fleas in her fur and scratching the fleas nonstop. I also got the cat version for my cats. I saw all of my pets start to increase itching after they first took the pill. Then I saw fleas stunned and paralyzed dropping on our floor tile. It absolutely works. We hurried washed the dog beds and vacuumed everything. I’m going to start giving this to my pets monthly. Yes I recommend it. ... show more

  • Would recommend
For what ever reason fleas have seen worse this summer in our area and our dog’s tropical treatment seemed not to be helping. We even treated the yard a few time too and she was catching fleas. I came across the product and saw it had some really good reviews and figure give it a try. So happy I did because it killed the fleas quickly after one dose!! I still check her daily just incase and so far, still no fleas. She hasn’t had any side effects either. ... show more

  • Works for only 2 days.
Not for long term relief…works for just a couple of days. Use something else for monthly relief. Made my cats vomit.

  • Works great at a great price
Been using for over a year my dog is not scratching anymore and there are no fleas and the great thing is is when I first started using it I had to give him a pill and then couple days later had to give him another to get rid of the eggs that hatch and then after that it kept the fleas off at once a month easy to use ... show more
