Interceptor Spectrum Tablet for Dogs (Yellow) in the 3-pack format is a three-month supply of the medium-dog Interceptor Spectrum dose. The yellow colour coding matches the 11 to 22 kilogram weight band, which covers most mid-sized Australian breeds.

Each chew provides monthly prevention of heartworm disease and treats and controls roundworm, hookworm, whipworm and tapeworm, including hydatid tapeworm. The chew format and chicken flavour are designed for voluntary acceptance as a treat rather than hidden administration. Interceptor Spectrum is safe for puppies from two weeks of age at any body weight, which makes it a practical household product where different-aged dogs need cover together.

The 3-pack Yellow is a common starter size for owners trying Interceptor Spectrum or covering a specific quarter. Owners stay on it because the narrow focus on heartworm and intestinal worms lets them pick their preferred flea and tick product separately, rather than being locked into an all-in-one bundle.
