The new interceptor pills have included an anti-tapeworm compound which will make interceptor a comprehensive dewormer for hookworms, roundworms, whipworms and tapeworms.
However, if the worm burden is high eg. the dog gets in contact with other dogs' faeces, the dog will still need to be dewormed separately. For example, if you take your dog out everyday, every 2-3 months, you will still need to do deworming. Try not to stick to just one brand for too long, resistancy may happen.
