Rated 4 out of 5 by Whackadoodle Works great. Can't buy it
My three dogs have been on this product for years. It works great. I like it because it takes care of all types of worms. I haven't been able to purchase it for the past two months because you have been out of stock. Very frustrating. Good product, but can't buy it!
