The gel texture is a key functional difference. Compared to heavier ointments or creams, a gel is lighter and less greasy. This makes it much more practical for application on hairy animals. It spreads easily and evenly through the coat without leaving a heavy, sticky residue that can mat fur or attract dirt. This easier spreading is useful for larger application areas where thorough coverage is desired. The formulation allows it to be massaged into the skin effectively while maintaining good contact, which is part of how the product works. For an owner, this means less product waste, easier cleanup, and an animal that is less likely to try and rub it off immediately. It's a format chosen for convenience and practicality in situations where you need to apply a topical product quickly and neatly.
