modamox dog application

  1. The dog should be standing for application. Part the hair on the back of the dog between the shoulder blades until the skin is visible. For dogs weighing 20 lbs. or less, place the tip of the applicator on the skin and apply the entire contents directly on the exposed skin at one spot between the shoulder blades. For dogs weighing more than 20 lbs., place the tip of the applicator on the skin and apply the entire contents directly on the exposed skin at 3 or 4 spots on the top of the backline from the base of the neck to the upper back in an area inaccessible to licking. Do not apply an amount of solution at any one location that could run off the side of the dog.

Do not let this product get in your dog’s mouth or eyes. Do not allow the dog to lick any of the application sites for 30 minutes. In households with multiple pets, keep each treated dog separated from other treated dogs and other pets for 30 minutes after application to prevent licking the application sites.

Stiff hair, a damp appearance of the hair, pink skin, or a slight powdery residue may be observed at the application site on some animals. This is temporary and does not affect the safety and effectiveness of the product.

Shampooing 90 minutes after treatment does not reduce the effectiveness of Midamox for Dogs in the prevention of heartworm disease. Shampooing or water immersion 4 days after treatment will not reduce the effectiveness of Midamox for Dogs in the treatment of flea infestation. However, shampooing as often as once weekly may reduce the effectiveness of the product against fleas.

Heartworm Prevention: For prevention of heartworm disease, Midamox for Dogs should be administered at one-month intervals. Midamox for Dogs may be administered year-round or at a minimum should start one month before the first expected exposure to mosquitoes and should continue at monthly intervals until one month after the last exposure to mosquitoes. If a dose is missed and a 30-day interval between doses is exceeded, administer Midamox for Dogs immediately and resume the monthly dosing schedule. When replacing another heartworm-preventative product in a heartworm prevention program, the first treatment with Midamox for Dogs should be given within one month of the last dose of the former medication.

Treatment of Circulating Microfilariae: For the treatment of circulating D. immitis microfilariae in heartworm-positive dogs, Midamox for Dogs should be administered at one-month intervals. Treatment with an approved adulticide therapy is recommended because Midamox for Dogs is not effective for the treatment of adult D. immitis.

Flea Treatment: For the treatment of flea infestations, Midamox for Dogs should be administered at one-month intervals. If the dog is already infested with fleas when the first dose of Midamox for Dogs is administered, adult fleas on the dog will be killed. However, reinfestation from the emergence of pre-existing pupae in the environment may continue to occur for six weeks or longer after treatment is initiated. Dogs treated with imidacloprid, including those with pre-existing flea allergy dermatitis, have shown clinical improvement as a direct result of the elimination of fleas from the dog.

Treatment and Control of Intestinal Nematode Infections: For the treatment and control of intestinal hookworm infections caused by Ancylostoma caninum and Uncinaria stenocephala (adults, immature adults and fourth stage larvae) and roundworm infections caused by Toxocara canis (adults and fourth stage larvae), and Toxascaris leonina (adults), and whipworm infections caused by Trichuris vulpis (adults), Midamox for Dogs should be administered once as a single topical dose.

Treatment and Control of Sarcoptic Mange: For the treatment and control of sarcoptic mange caused by Sarcoptes scabiei var. canis, Midamox for Dogs should be administered as a single topical dose. A second monthly dose may be administered if necessary.


Store below 77°F (25°C). Excursions are permitted up to 104°F (40°C) however such exposure should be minimized. Do not remove the applicator from the pouch until ready to use. Do not use after the expiry date which is stated on the carton.
