When a dog can get poisoned

Isoniazid (Tubazid) is a drug for the treatment of tuberculosis. The tablets containing it are freely available. For humans and most animals, they are non-toxic, but for the representatives of the dog family, they present a serious danger. This is due to the lack of a specific enzyme that destroys the drug. There are reports that cats also suffer from poisoning with isoniazid, but for them the drug is dangerous in a much higher dosage.

Another scandal erupted in 2010, when the authorities of Donetsk and Lugansk regions used a drug to combat stray dogs.

Enter intravenously in a dose equal to the amount of poison taken. If the amount of isoniazid is unknown, Pyridoxine is administered at a rate of 50 mg per kilogram of live weight. Or in an amount of 3-5 grams per animal (ie from 30 to 50 ml of 1% solution). If there is no possibility of intravenous injection, colitis with intramuscular injection. If there is convulsions, then injected for 5 minutes, and if they are absent - within half an hour. Seizures after injection usually stop, but the mind can remain confused for a while (several hours).
