“living in a state with a big tick problem, I chose nexguard over the topicals because my dog would get sick a few days later when using them. this is a prescription drug. Allivet has done a great job helping me get this filled. this is the second year I ve used there online service. Next year I will start having them contact my vet to get the prescription direct. its part of there service, and will speed up getting the drug my dog needs faster. great service people, very helpful.”
