You may use Nexgard or Simparica in place of Comfortis as both these treatments protect against fleas and ticks for one month. Consult your vet before using them on your pet.
My rescue dog throws up only when she is given trio type preventative. Flea, tick and heart worm. My other rescue dog is fine. Is there anything more gentle on her stomach?
