  • Flea & Tick
    Great Product! No fleas or ticks on dogs or in the yard. No side effects! by on 02/04/2019
  • Works Perfectly
    We use a Sentinel heartworm medicine that also eliminates fleas, and this flea medicine only make it extreme on protection. We have been around dogs and cats that did have fleas and our dog has not had 1 single flea touch him. The double wammy of meds keeps him flea free. by on 12/03/2018
