Barrier Topical Solution for Dogs 9.1-20 lbs
(Imidacloprid + Moxidectin)
Barrier for Dogs 9.1–20 lbs is a prescription-strength topical parasiticide formulated with Imidacloprid and Moxidectin to deliver broad-spectrum parasite protection for dogs weighing between 9.1 and 20 pounds. This once-a-month topical solution not only kills fleas but also prevents heartworm disease, and treats intestinal parasites like roundworms, hookworms, and whipworms. It's also effective against sarcoptic mange caused by mites.
Barrier works both systemically and topically: Imidacloprid targets fleas through contact, while Moxidectin is absorbed transdermally to act against internal parasites and circulating Dirofilaria immitis microfilariae (the parasite responsible for heartworm disease).
Ideal for multi-parasite protection in a single dose, it’s comparable to Advantage Multi, but at a more affordable price point—making it a smart and economical option for year-round protection.
Prescription items are NON-RETURNABLE and NON-REFUNDABLE.

Barrier for Dogs 9.1–20 lbs FAQs
Can Barrier be used year-round?
Yes, monthly year-round use is recommended to protect against fleas, heartworms, and intestinal parasites, especially in warmer regions where parasites are active all year.
What happens if I miss a dose of Barrier for my dog?
If a dose is missed, apply immediately when remembered and resume monthly schedule. Gaps in treatment may leave your dog vulnerable to heartworm and fleas.
Is a prescription required for Barrier?
Yes. Because it includes Moxidectin (a heartworm preventive), Barrier is classified as a prescription medication and must be obtained through a licensed veterinarian.
How long after application can my dog swim or bathe?
It is best to wait 48 hours after application before bathing or swimming to ensure the solution is fully absorbed and water-resistance is effective.
Can I apply Barrier if my dog is already on a dewormer?
Consult your vet. Barrier treats hookworms, roundworms, and whipworms, so using additional dewormers may not be necessary unless treating a specific infestation.
