Nic its a confusing world of worming/flea treatments for dogs and cats nowadays. Everyone will have their favourite & think theirs is the best! The one thing is to steer clear of non brand name ones... because sometimes the supermarket ones have organophosphates which is a toxin for some animals.

I use: drontal for intestinal worming, heart guard for heart worming and advantage for flea treatments. Drontal is a tablet, heart guard is a chew and advantage is a top spot.

now-a-days there are heaps of top spots which do all three functions. They generally seem expensive, but if you compare the value monthly, its pretty average. Advocate and Revolution do everything but tapeworm.... but tapeworm is spread from fleas so if they are treating fleas, they reckon that they are treating tapeworm at the same time. Unfortunately it takes 1 flea bite to spread tapeworm. BUT tapeworm is the easiest fix, you just pop to the vet & get a tapeworm tablet over the counter.

I don't use the topspots because I get free heartguard.
