## Before you buy

- Keep the collar on continuously during the stated 7–8-month period, check and readjust the fit periodically, and avoid prolonged intense water exposure or extensive shampooing because these may reduce activity duration. The listing also cautions that tick attachment and disease transmission cannot be completely excluded in unfavourable conditions.
- The listing names flea and tick control and a 7–8-month period, while customer feedback reports mixed durability, with some saying it lasted around four months. Customer reports also include both skin irritation and no more scratching, so neither an individual outcome nor the claimed duration is assured. Follow the product directions and consult a veterinary professional if concerned about irritation.

## A good fit for

- Owners of dogs over 8kg seeking a collar-based flea and tick treatment with less frequent scheduled replacement than monthly treatments.
- Buyers who prefer an unscented collar applied around the neck rather than a topical product.

## Less suited to

- Dogs weighing 8kg or less, as the selected size is listed for dogs over 8kg.
- Owners who need a treatment that can be expected to retain its full stated activity despite prolonged intense water exposure or extensive shampooing.

## Customer feedback

Customer feedback reports perceived effectiveness and some owners say their pets seem happier and more settled. Reports about durability are mixed, including accounts of collars lasting months and around four months, while experiences with skin irritation also differ. Value is likewise divided. For buyers choosing this collar for its claimed 7–8-month interval, the mixed duration reports are relevant, and irritation feedback is a reason to monitor the dog's skin rather than assume a uniform response.

- Positive themes: Some customers say their pets seem happier and more settled while using it.
- Negative themes: Some customers report skin irritation.
- Negative themes: Some customers say the collar lasted around four months.
