My Bee is on a monthly treatment of frontline plus and heartgard plus since he is 5 months old. A few days ago I noticed a white piece in his stool, took it to the vet and he has tapeworm. I don't find any flea on him and don't know how he got tapeworm. This is the first time for him.
May be frontline plus is not effective?
Any advice what product I should use considering he has CM and PSOM.
