I was thinking of switching Sprocket to Comfortis just to change out but his weight fluxes between 10-12 lbs, the vet wants to up the weight limit to the med sized dog, over 10lbs, but Sprocket doesn't always weigh that, we have always used a topical before and had good results, I just thought it might be a good thing to change it out. And So Cal is all ways the time of year for fleas and ticks
, any thoughts???? Thanks.
