Abstract
Recently grievances and petitions have been aroused by the inhabitants of Tokyo that pharmaceutical destruction of stray and ownerless dogs be carried out as they have been threatening people and domestic animals as well during night. According to the Rabies Prevention Law, however, no pharmaceutical destruction of strayed dogs shall be enforced except during the period which is officially announced from a special need for preventing the spread of rabies and eradicating the infected dogs. Such being the case, it has become necessary to capture dogs in a state of anesthesia by allowing them to have bait containing anesthetic perorally.
Experiments were performed on 513 dogs captured and passing the legal period of detention, with bait of meat containing each of 8 proprietary anesthetics, pentobarbital, phenol-barbital, barbital, orthopan, evipan, sulfonal, chloral hydrate, and brobarin. When a dog was given the following anesthetics in such doses as mentioned, it was anesthetized in 30minutes and waked up in 6 hours, without suffering death.
Single preparation: pentobarbital, 0.2 to 0.5g.
Mixed preparations:(1) pentobarbital plus brobarin, (2) pentobarbital plus evipan, and (3) pentobarbital plus orthopan, 0.3 to 0.5g each.
The results indicate that this form of capture using anesthetic is available for practical purposes.
