Bravecto is the best product, don’t fuck about with Frontline because it’s shit. 1 tablet for a dog that size will cost you about £21 though, obvs, you should pay as you’re to blame here. There are many preventative repellants that are natural, crushed bay leaves for one. Also, tobacco works so you if you are truly fond of the animal I believe that you should start smoking 200 Capstan full strength a day and breathe on the Cunt.
