Flea and Tick Prevention for Dogs, 6 Months Supply Dog Flea and Tick Treatment Up to 45 to 88 Lbs, Waterproof Topical Flea Treatment for Large Dogs - Fast-Acting Flea, Tick, and Mosquito Repellent

This 6-month topical formula targets large dogs (45-88 lbs) with a waterproof application that resists bathing within 48 hours. The fast-acting ingredient profile tackles fleas, ticks, and mosquitoes simultaneously, which is practical for multi-threat environments. Application is straightforward—part the fur at the neck base and squeeze the tube directly onto skin. Results appear within 24-48 hours for fleas and tick prevention. However, some dogs exhibited minor skin irritation at application sites, and the formula's waterproofing claims work best when applied to completely dry coat. The 6-month supply represents decent value against monthly alternatives, though efficacy varies depending on local parasite pressure and individual dog sensitivity.
