Hartz UltraGuard Pro Flea and Tick Topical Treatment, 6 Months, 5-14 lbs, Dogs & Puppies

Each month, empty one tube of these flea drops for dogs onto the skin: the package holds six single-dose tubes, so a full pack covers six monthly applications. The label lists etofenprox as the active ingredient. According to the manufacturer, the formula destroys deer ticks, brown dog ticks, flea larvae, flea eggs and fleas as soon as they touch it. Mosquitoes are kept away prior to biting.

What the treatment does and how it spreads

The same label text says re-infestation is prevented for 1 month after each application. Two Insect Growth Regulators are included in the formula alongside the active ingredient etofenprox.

After application, the product spreads across the skin and travels over the coat using the dog's natural oil, as described by the manufacturer. The formula is labelled as quick drying and described as staying on without rubbing off. The tube has a patented Pro-Glide angled applicator with rounded edges, and the maker lists the treatment as suitable for both long-haired and short-haired dogs.

Six tubes in the package

Each package holds 6 single-dose tubes, and the maker describes the pack as a six-month supply because one tube is used per monthly application. The package measures 5 x 15.7 x 11.9 cm (2 x 6.2 x 4.7 in) and weighs 45 g (1.6 oz) as shipped.

Does it fit your dog?

The label sets the weight range at 5 to 14 pounds, so check your dog's weight on a scale before you buy a tube. Puppies must be at least 12 weeks old.

Cats and kittens are excluded by the manufacturer, so this product is not for them. If your dog's weight falls outside 5 to 14 pounds, the size does not match this version. Both long-haired and short-haired dogs are listed as suitable.

The active ingredient and IGRs

Etofenprox is named as the active ingredient on the label. The formula also contains dual Insect Growth Regulators, which the manufacturer lists as part of the treatment alongside etofenprox.

Applying the drops

The directions call for one tube per monthly application, which gives six applications from the six-tube package. The manufacturer states that the liquid spreads across the skin, moving over the coat with the dog's natural oil. The angled Pro-Glide applicator has rounded edges and is used to empty the tube onto the skin.

The quick drying formula is described as staying on and not rubbing off after application. The manufacturer says re-infestation is prevented for 1 month following each dose, which lines up with the monthly schedule of the six tubes.
