Tick Medicine Poisoning in Dogs



In the less severe cases of Amitraz toxicosis resulting from topical application, mild sedation after the application of properly applied solutions, or a gloved scrubbing with a dish-washing detergent and large amounts of water may be sufficient as a treatment. More severe cases may require one to two days of inpatient care and supportive therapy consisting of intravenous fluids, nutritional support, and the maintenance of normal body temperature.


If the condition was caused by the ingestion of a collar, then the larger pieces have to be removed from the stomach with an endoscopic retrieval.


In the case of a collar ingestion during which the dog is not yet exhibiting any of the symptoms of Amitraz toxicosis, a 3 percent emetic and USP hydrogen peroxide (2.2 ml per kilo of body weight, maximum 45 ml) is orally administered after a moist meal has been fed. Activated charcoal (2 g per kilo of body weight) that contains sorbitol may also be administered through a stomach tube every four hours until the pieces of the collar bone appear in the dog's stool.


If the dog is exhibiting marked depression, there are several medications available that can be used until the dog starts showing signs of improvement. An elderly, sick, or debilitated dog may need more time to recover from the symptoms.


Living and Management


After successful treatment, the dog must be closely observed for 24 to 72 hours and its body temperature, blood pressure, serum glucose and heart rate must constantly be monitored. In extremely severe cases, medications may need to be re-administered. There are usually no long-term adverse effects after the condition has been successfully treated.




The best prevention for Amitraz toxicosis is to follow the instructions that come with the topical solutions and tick collars accurately, and to keep dogs in the same household from licking each others’ collars. Also, owners must keep Amitraz-containing solutions and unused tick collars in a place that is not accessible to their dogs.
