Overview
["This shampoo is built around Precor, an insect growth regulator, alongside coconut extract, and it's labeled safe for both dogs and cats, including puppies and kittens 12 weeks and older. That dual-species labeling makes it a convenient pick if your household has more than one type of pet.", 'At 6 oz, the bottle is on the smaller side compared to others in this roundup, so the $10.99 price runs a bit higher per ounce, but the formula is built to target flea eggs and lice in addition to adult fleas and ticks, which is a broader scope than some competitors here.', 'The numbers back up the reputation: 32,921 reviews averaging 4.4 stars and roughly 3,000 bought in the past month make this by far the highest-volume shampoo in this category, reflected in its number one ranking among Dog Flea Control Shampoos.']

Performance notes
The Precor active ingredient is an insect growth regulator, meaning it targets flea eggs and larvae in addition to adult fleas, ticks, and lice, a more complete life-cycle approach than the tick-and-adult-flea-only formulas elsewhere in this roundup. Coconut extract is included to help clean and condition the coat while bathing, rather than leaving it dried out from the treatment.

Precor is an insect growth regulator that targets flea eggs and larvae in addition to adult fleas, ticks, and lice, giving broader life-cycle coverage than a shampoo that only kills adult pests.

How big is the bottle?
