## Before you buy

- The listed weight and volume appear unusually large for a six-pipette treatment, and the age descriptor says Puppy while the title specifies large dogs weighing 20–40kg. These listing details are inconsistent, so confirm the selected pack's labelling and suitability before purchase. The flea and tick kill times and six-month duration are listing claims, not independently verified results.

## A good fit for

- Owners seeking a six-month supply of monthly spot-on treatment for a large dog weighing 20–40kg.
- Buyers who prefer a liquid treatment applied at the back of the neck.

## Less suited to

- Dogs outside the stated 20–40kg range.
- Buyers who need confirmed age suitability without checking the product packaging or veterinary advice.

## Customer feedback

Aggregate ratings are mostly five-star, with a smaller spread across lower star categories. This indicates a generally favourable overall rating but does not establish why customers rated the product as they did or resolve the listing's inconsistent age, weight and volume details.
