    We used this for our German Shorthaired Pointer about 6 months ago when he got a hold of a rabbit. Worked like a charm! Having to buy it again because he got a hold of another rabbit!

    I bought this for my 8 year old Husky. It was his first time getting worms, so I wasn't sure which product to try. I tried a cheaper liquid wormer at first to no avail. I immediately ordered this because of its reviews. Within a day of taking this dewormer by Bayer, the worms were dead. It took about another day until his stool was completely free of dead worms and normal colored. I did notice some blood in the stool, but it was listed as a possible side effect. The issue subsided after a day.

  • Well it tastes good...

    Apparently my dog Kane thinks this dewormer is amazing because he ate through the package to get to it. Thankfully, he only ate the proper dosage. Beef flavor=Kane approved! He also has a very sensitive stomach and it didn't cause WW3 so another positive in my book. I am giving this 4 stars currently because I'm waiting on test results to be sure it worked. However, I'm assume it did.
