Monthly 6-in-1 Spot-On for Heartworm, Fleas and Parasites in Small Dogs

Product Description

Barrier Topical Solution (Teal/Ice Blue Box, 9.1 to 20 lbs) is an FDA-approved, prescription-only monthly spot-on for dogs and puppies 7 weeks or older weighing 9.1 to 20 lbs. Each 1.0 mL tube delivers 10% imidacloprid and 2.5% moxidectin, the same active ingredients as Advantage Multi for Dogs.

Benefits

• Prevents Heartworm Disease: Moxidectin prevents Dirofilaria immitis larval development into adult heartworms when applied once monthly to small dogs.

• Kills Adult Fleas: Imidacloprid kills adult fleas fast, providing effective flea treatment and preventing flea infestations with each monthly dose.
• Treats Intestinal Worms: Effectively treats and controls intestinal infections caused by hookworms, roundworms, and whipworms in small dogs.
• Treats Sarcoptic Mange: Treats and controls sarcoptic mange (Sarcoptes scabiei) infestations in small dogs with each monthly topical application.
• Single-Spot Application: The entire tube is applied in one spot between the shoulder blades, making monthly application quick and straightforward for small dogs.
• Same Ingredients, Better Value: Contains the same active ingredients as Advantage Multi for Dogs, offering equivalent six-in-one parasite protection.
• Made in the USA: Manufactured and packaged in the USA from a registered FDA facility, ensuring quality and regulatory compliance.

Frequently Asked Questions

Q1: What does Barrier Topical Solution (Teal/Ice Blue Box) treat and prevent in small dogs?

Ans: Barrier Teal/Ice Blue Box is a monthly 6-in-1 spot-on for dogs 9.1 to 20 lbs that prevents heartworm, treats circulating microfilariae, kills adult fleas, treats flea infestations, controls hookworms, roundworms, and whipworms, and treats sarcoptic mange in dogs and puppies 7 weeks or older.

Q2: Why is the Teal Box applied in one spot while larger dogs need multiple spots?

Ans: For dogs 20 lbs or less, the small volume absorbs effectively in one spot between the shoulder blades. For larger dogs, applying one spot causes pooling and reduces absorption, so 3 to 4 backline spots are required for complete coverage and optimal efficacy.

Q3: Can the small dog spot-on treat a heartworm-positive dog?

Ans: Yes. Barrier for Dogs is indicated for treating Dirofilaria immitis circulating microfilariae in heartworm-positive dogs. It does not eliminate adult heartworms, so veterinarians may also recommend adulticide treatment to remove existing adult worms alongside the microfilariae treatment protocol.

Q4: How does the Teal Box differ from the Green Box for extra-small dogs?

Ans: The Teal Box contains 1.0 mL delivering 100 mg imidacloprid and 25 mg moxidectin for dogs weighing 9.1 to 20 lbs. The Green Box contains 0.4 mL delivering 40 mg imidacloprid and 10 mg moxidectin for dogs 3 to 9 lbs. Both offer identical six-in-one protection.

Q5: Is the small dog monthly spot-on safe for pregnant or lactating dogs?

Ans: Barrier for Dogs has not been tested for safety in breeding dogs or those that are pregnant or nursing. If your small dog is pregnant, nursing, or intended for breeding, always consult your veterinarian before starting any parasite prevention program to determine the safest and most appropriate option.
