Talk to Your Veterinarian Before Buying
I never buy parasite prevention without asking my vet first. That was especially true when I was choosing something for a small dog. My vet helped me confirm whether Simparica Trio was appropriate based on my dog’s age, weight, health history, and any other medications. I found this step really important for peace of mind.
