Removing the tick while still alive is the preferred way as a dying tick may regurgitate fluids and increase the risk of transferring Lyme Disease. Be careful not to squeeze the body of the tick for the same reason. To remove them, grip below the body as close to your dog's skin as possible using long finger-nails or tweezers then pull and twist to release. Try to ensure the head of the tick is removed as well as the body. Dab with a mild antiseptic and wash hands afterwards. Ideal for cats dogs rabbits etc. Price £2.99 including p&p
