Having successfully de flead the house and cats I'm now looking for the best treatment to use on our big furball. He's 22 week old long coat Akita. I used Wilkies spot on treatment a couple of weeks back but he's still scratching away. Is frontline and advantage still the best? and what format is best tablet or spot on? Going to take him to pets at home to get weighed but will probably shop around online for best prices on treatment.
