Query: Best Pup wormer ever!

I bought this wormer to worm my liter of German Shepherd puppies. This is so easy to use, and I guess the taste is pretty good too, because the pups will take it straight. Its much better than other products I have used in the past, only requiring a worming every two weeks. If you have a liter of pups to worm, try this product! It will save you time, and money.
