Barb, it's Frontline Spray Treatment. 17 oz. spray bottle (500 ml). We get it directly from our vet. but I think I recently saw it advertised from Lion Supply. Instructions from Vet. is to apply 20 pumps to head and neck area every 30 days. As I stated we stagger the applications in between the liquid topical Frontline Plus. That way the dogs are getting either one or the other on a 15 day rotation.
