What kind of reactions did your furbaby have with the topical? My boy used Comfortis for 3 months and had a reaction. He used it fine the first month but then had reactions the next two months so I switched him back to the topical stuff. I'm not sure why he didn't take the Comfortis well. It might have been that he weighed a little less than the med called for. Not sure but he has been fine with the topical stuff. |
