FAQ
Your veterinarian is best suited to discuss and recommend appropriate medications for your dog. It is important to discuss your pet's health history with your veterinarian so he/she can decide if Barrier® is right for your animal. Barrier® should not be used in sick, debilitated or underweight animals. Dogs should be tested for heartworm disease prior to giving Barrier®. If your dog tests positive for adult heartworms, your veterinarian can recommend appropriate treatment. If your dog is older than six months of age, your veterinarian may decide to test him/her for heartworm disease before prescribing Barrier®.
Your veterinarian will recommend the appropriate dose for your dog based on its body weight. Do not administer Barrier® to dogs younger than 7 weeks of age or weighing less than 3 lbs. Barrier® is available in a variety of dose sizes for dogs of different weights.
If you forget to apply a monthly dose of Barrier®, immediately apply Barrier®, resume monthly applications, and notify your veterinarian.
Contact your veterinarian if you administer more than the prescribed amount of Barrier®.
- Remove the Barrier® tube from its protective package.
- While holding the tube in an upright position, twist the cap to break the seal. The cap will remain on the tube.
- Barrier should be applied to the top of the neck between the base of the skull and the shoulder blades.
- Apply the tip of the Barrier® tube directly to the skin by parting the hair. Squeeze the tube firmly 3 to 4 times in one spot until it is empty. Keep the tube compressed on the final squeeze to avoid drawing liquid back into tube. Avoid contact between Barrier® and your fingers. Do not massage Barrier® into the skin. Do not apply when the haircoat is wet. Do not apply to broken skin. Stiff hair, clumping of hair, hair discoloration, or a slight powdery residue may be observed at the application site in some animals. These effects are usually temporary and do not affect the safety or effectiveness of the product.
Yes. Bathing or shampooing your pet 2 or more hours after application will not reduce Barrier’s ability to prevent heartworm disease. Waiting to bathe your pet for 24 hours after application with ensure optimal flea protection.

This medicine doesn’t take care of fleas and I’m thinking it doesn’t cover heartworms . My dog is 11 and has taken heart guard advantage most all his years. I changed to this a year ago and he now has heartworms. When I bath him and his sister I’ve found several fleas when I didn’t before using Barrier! I’m very upset right now.
