    Depending upon your dog's size and the size of the medication he ate this may be fine or it may be a toxic amount. A nontoxic dose would be 0.5mg to 2.0mg per kilogram or 0.22mg to 0.9mg per pound. That means a 15 pound puppy could eat 13.5mg of milbemycin without any effect. There are reports of dogs ingesting 20 times the labeled dose without any problems but five tablets of any but the smallest size (brown or 2.3mg per tablet) of the sizes available would be more than the recommended dose and could lead to side effects. Some dogs are more sensitive than others and you don't know if your dog is a sensitive dog or not. Because of this you may want to induce vomiting by giving him 1ml of peroxide per pound of body weight orally (15mls or 1 tablespoon per 15 pound dog). Take him outside and let him run around. If after 10 minutes there isn't any vomiting repeat the dose.

    Side effects of high doses of this medication are dilated pupils, salivation (drooling), lethargy, ataxia (unsteadiness and difficulty walking), fever, seizures, coma and death. If he becomes symptomatic he needs to seen as soon as possible for supportive care by a veterinarian.
