If the package has only 6 tablets, do I need to purchase 2 packages to complete the 7-day treatment?

Worked well for dozens of shepherds, numerous times.

This is a much easier solution. Fenbendazole has it's uses, and for certain worms or bacteria is a required solution. However using it is a real chore when you have 6+ dogs at any given time, as you need to properly dose the poweder three times a day. This is incredibly easy. 1 tablet for any dog under 50 lbs, 2 tablets for my pups 50-100... .done. one shot, one treatment day. easy to just let them out one at a time and give it to them. Some dogs are picky so i'll break it up and add it to can food. Doing that seems to hide it well enough. To those who say "it made my dog have loose stool" or similar, you should consult a vet if in doubt, but that is NORMAL when it KILLS OFF a large amount of parasites. If your dog passes a whole bunch of nasty after getting one of these, congrats, you just cleaned out a lot of junk that shouldn't be in there. Give a pro-biotic a few days after of your choice, then deworm again a month later like the package recommends. First time I saw this flush out parasites my regular dewormer must have missed, i was taken back by the smell and gross-ness as well. Do your research for your particular ailment, but in most cases that's a good thing. Be sure to sanitize thoroughly (bleach) anywhere they defecate to prevent any re-infestation from eggs that might survive it.

Made all my dogs terribly ill!

I decided to try this product because of the ease of 1 time dosing with a chew tablet rather than the usual 3 day dosing of the Safeguard powder I normally use. This was a terrible mistake, every one of my 4 dogs I gave this product to got very sick a few days after taking with explosive watery diarrhea, vomiting, lethargia. I recommend this product be taken off the market if it makes dogs sick like it has done mine. Beware! I am going back to Safeguard which has Always been effective and has never made any dog I have given it to sick like this.

Great Wormer

Very good price and received very quickly. Furbabies ate the pills well and package was actually easy to open.

Looks good.

I gave my dog the wormer at the first sight of a tapeworm segment. I have no idea how he was exposed. I am diligent about flea control. No new segments. Yay!

Necessary and Effective!

Rudy is a Carolina Dog, also known as a landrace dog, with the run of a small yard. It has a wealth of squirrels, rabbits, chipmunks, birds, and an occasional fox. Despite telling him NO CRITTERS whenever I let him out, because he is temperamentally headstrong, which is characteristic of the breed, I have discovered evidence and witnessed one kill from the window. Just one of these monthly has kept him healthy, and I always keep a supply on hand. This review was edited to remove parentheses and quotation marks. There NEVER was an emoji to be removed. Chewy has a WEALTH of website issues that need to be REMOVED, another reason for fewer stars.

It Worked

After reading negative reviews, I was unsure about purchasing this product. I decided to give it a try since the dogs had worms and needed relief. I treated 3 dogs, each weighing about #50 and it was effective for all 3. Glad to report that it took care of our worm problem.
