Interceptor Spectrum for Medium Dogs in the 3-pack is a three-month supply of monthly worming chews dosed for the 11–22kg weight tier. It suits owners new to the product or topping up an existing routine without committing to the larger six-pack supply.

Each chicken-flavoured chew combines milbemycin oxime and praziquantel: milbemycin prevents heartworm and treats roundworm, hookworm, and whipworm, while praziquantel covers all common tapeworms including hydatid tapeworm. Designed to be eaten voluntarily as a treat, the chew avoids the wrestling match that often comes with monthly pilling. Safe for puppies from 2 weeks of age, plus breeding, pregnant, and lactating dogs.

Three-pack worming runs are the easy way to test whether a dog will eat a new chew before stocking up, and most dogs accept Interceptor Spectrum without coercion. The combination of broad parasite coverage and palatability is what keeps it on most vet-recommended worming lists.
