Rated 5 out of 5 by Terri64 Awesome to have it all in one pill.
So nice to just give my dogs one pill for the month and have it cover everything.

Rated 4 out of 5 by doggymommy all in all, it does what it's suppose to.
I have a hard time getting my dog to take it. I have even coated it in peanut butter. He licks it off and then spits it out. It really smells bad so I don't blame him.

Rated 5 out of 5 by Jorie Trifexis works great
I have three girl dogs: a 16year old shepherd mix, a 5 year old beagle mix, and a 5 year old schnauzer mix. We have lived in numerous places around the world and successfully used Heartgard and K9 Advantix II. Until we got to Florida and this past summer the fleas were relentless and nothing topical worked. The dogs were miserable and so were we. Until we tried Trifexis. Within 30 minutes the fleas were gone and they have not returned. The dogs had no adverse reactions and they tolerate it well. The only complaint is that it is ridiculously expensive.

Rated 3 out of 5 by Bill7501 Product keeps dogs healthy
I have used this with my two labs for over two years. It is very effective but the dogs hate the taste. I have tried putting it in meat, pill pocket treats, peanut butter, chicken stock, sardines and cheese, things they normally love. Every month I have to hold their mouths open and force them to take the pill. They are on other vitamins which they take willingly and without fuss but Trifexis NO.

Rated 4 out of 5 by newfielover I like the convenience of Trifexis
Great product to combat multiple problems that happen
to pets. Use to use Comfortis (made with same drug to
combat fleas) but now this is combined to help
Product is expensive, but my 3 big dogs are worth every
