Heartworm, Worming and Flea Spot-On for Medium Dogs

Imidacloprid is a neonicotinoid insecticide used in topical flea treatments for dogs. It acts on the nervous system of fleas by binding to nicotinic acetylcholine receptors, causing paralysis and death within hours of contact.

Moxidectin is a macrocyclic lactone used to prevent heartworm and treat a range of internal and external parasites. It works by disrupting nerve signal transmission in parasites, and is available in both oral and topical formulations.

Unknown ingredients refer to components listed in pet food formulations whose specific identity or source is not disclosed. These may originate from animal, plant, or synthetic sources. Their primary purpose can vary, including nutritional supplementation or functional roles such as preservation. As their exact form is unspecified, it is unclear whether they are used in their natural state or as processed compounds, raising concerns about transparency and traceability.

This ingredient is included as a cost-effective component or processing aid, potentially serving to optimise manufacturing efficiency or product texture. Its presence may also support labelling requirements or contribute to the product’s stability, though its specific functional role is not clearly defined.
