What is the only method of euthanasia permitted for dogs and cats in Texas animal shelters?

The only method of euthanasia permitted for dogs and cats in Texas animal shelters is sodium pentobarbital. This drug is an anesthetic agent that acts quickly to induce unconsciousness and is used specifically for humane euthanasia because of its effectiveness and the rapidity with which it causes death.

Sodium pentobarbital is recognized for its ability to safely and painlessly end the life of an animal, making it the preferred choice in shelter settings where humane treatment is a priority. Its use also aligns with ethical guidelines and regulations governing animal welfare. In contrast, the other substances listed do not meet the same standards for use in this context; for example, carbon monoxide is not considered humane and can cause prolonged suffering, while chloral hydrate and phenobarbital are not typically utilized or endorsed for euthanasia in shelter settings in Texas.
