  • It works if the dog will eat it.
    I need to buy something else because my dog hates it. Today I cut up the pill (50+ lb size) into 8 pieces and hid the pieces in roasted hot dog bits and he still hesitated- and given that I can still smell the pesticide smell on my fingers from cutting it up, I don’t blame him. The pill is too large to shove it down his throat whole - about the size of two nickels stacked. If you have a greedy fast eater with weak taste buds, I’m sure it’s great, but it’s a stressful ordeal for me that I’d like to avoid in the future. by on 06/02/2019

    Seems to do the job. My dog hates the taste so I have to push it down her throat and give her a treat immediately after but that works. by on 02/21/2019
  • worng size tabet
    We ordered the pill indicated for the cats size. The pill that arrived is much larger than the ones we purchased from the vet. It is monthly torture to get her to take it. It did arrive fast. by on 01/30/2019
