Frontline also has a spray-on protection now. It is very economical. The smaller bottle is about $24 and last a long time. You put one spray on for every 2 pounds of weight. I use this with my herd. It is the same medicine as the Frontline (fripinol). My vet also told me that I could split the doses of the regular Frontline and also the Heartgard. I use 1/2 of the Heartgard "treat" for each dog 6 pounds and under. |
