I have 3 dogs..all giant breeds..Saint bernards and an English Mastiff Pot belly pigs... goats.. maybe even my cats for tapeworm.. I'm sick of going to the vets and spending a million bucks when TSC sells stuff...i just DONT KNOW WHAT IS REALLY SAFE TO USE.. Is there a wormer that can safely be used for all these animals? I've read something about ivermectin?? Is that horse or cattle? or what should i use? thanks.. Also..i DO have Wazine17...but i dont think it gets rid of tapeworms.. and i dont think dogs/cats can have it..can they??
