The 12 oz bottle size provides a reasonable amount for multiple treatments, and the product is allergen-free, making it safe for pets with sensitivities.

The dosage and administration instructions should be followed carefully to ensure safety, particularly for younger or less healthy pets.

This dewormer is allergen-free and made in the USA, which can be reassuring for quality.
