Flea and heart worm meds. My vet wants me to put lily on sentinel this spring after her heart worm test.She is on Vectra now just for the fleas.Is this stuff safe?I would like a combo pill that does the fleas and heart worms,ticks are not a problem in my yard.Is this the best kind or is there a better one?The Sentinel is only 10 bucks compared to the 17 bucks it cost me for the vectra!So thats a big plus seeings how i am currently laid off. |
