ProVET Insectostop, 70 cm is an insecticidal and acaricidal collar for dogs from the Ukrainian brand ProVET. The active ingredient is 4.0% fipronil. It's used to prevent and treat diseases caused by ectoparasites: fleas, ixodid ticks (Dermacentor, Rhipicephalus, Ixodes ricinus), lice and chewing lice. Worn continuously, it protects for at least 4 months.
What it is and how it works
The collar is a polymer strip with a buckle, impregnated with fipronil. While it's worn, the active ingredient gradually spreads over the skin and coat and kills parasites that get onto the dog. Fipronil acts on the nervous system of insects and ticks. The collar has a specific smell from the active ingredient, which is normal. The 70 cm length is designed for dogs and is adjusted to the neck size.

How to fit it
Take the collar out of the pack, straighten it and fasten it loosely around the dog's neck so two fingers fit easily underneath. Thread the end through the buckle and adjust the length. For growing puppies, leave extra length to loosen it as they grow; for adult dogs, cut off the excess so they don't chew it. Wear the collar continuously, as that's the only way it protects for the full period. Before use, keep it in its sealed pack at 5–25 °C, out of children's reach.
Combined flea and tick protection
Ixodid ticks carry dangerous diseases, including babesiosis (piroplasmosis), so even with a collar, check your dog after every walk through grass or woods, especially the head, ears, neck, armpits and groin. Remove any tick with a tick hook. Fleas spread tapeworms, so flea control goes together with regular deworming. More in protecting your dog from fleas and ticks and worms in cats and dogs.
Compared with other collars
For longer protection there are collars lasting 7–8 months, such as Foresto. Another option is Kiltix. If a collar is inconvenient, spot-on drops such as ProVET ProfiLine are an alternative. Don't combine different insecticides without your vet's approval.
Who it suits
Dogs over 3 months old needing seasonal protection from fleas, ixodid ticks, lice and chewing lice, especially when you want an affordable, simple option for several months. Other products are in parasite control.
Verdict
ProVET Insectostop is an affordable fipronil collar that protects a dog from fleas, ticks, lice and chewing lice for at least 4 months. A simple seasonal solution as long as you fit it correctly, respect the contraindications and keep checking your dog after walks.
If irritation appears or the dog seems unwell
Watch your dog for the first few days after fitting the collar. If the skin underneath turns red, or itching, scratching or hair loss appear, remove the collar and wash the skin with water and a mild shampoo. With drooling, vomiting, lethargy or trembling, especially if the dog has chewed part of the collar, see a vet immediately and take the packaging with you. Don't let children play with the collar, and wash your hands after fitting it. In multi-dog homes, make sure dogs don't chew each other's collars.
