 FDA Report on the Risk from Pentobarbital in Dog Food
Pentobarbital seems to be able to survive the rendering process.
However, to get to the exposure level of 50 micrograms of pentobarbital per day, which is the highest level at which no biological response was seen, a dog would have to consume between 5 to 10 micrograms of pentobarbital per kilogram of body weight.
During the 1990s, FDA’s Center for Veterinary Medicine (CVM) received reports from veterinarians that pentobarbital, an anesthetizing agent used for dogs and other animals, seemed to be losing its effectiveness in dogs.

 pentobarbital - [Medication]
Pentobarbital is used to treat insomnia (for up to 2 weeks) and to induce sleep before surgery.
Pentobarbital is habit forming, which means that you can become addicted to it.
Your pharmacist has more information about pentobarbital written for health professionals that you may read.

 General Statement Regarding Euthanasia Methods for Dogs and Cats HSI Electronic Library
Employees must be able to cope emotionally with euthanizing large numbers of animals while maintaining a concern for the well-being of each individual dog or cat.
The term "euthanasia" is derived from Greek, meaning "good death." In order to be humane, every euthanasia technique must result in painless, rapid unconsciousness, followed by cardiac or respiratory arrest, and ultimately death.
This method, when properly performed, has been found to be the most humane, safest, least stressful, and most professional choice by The HSUS, The American Humane Association, and the American Veterinary Medical Association.

 Pentobarbital Sodium
Drug Interactions - Most clinically significant interactions have been documented in hu­mans with phenobarbital, however, these intreactions may also be of significance in ani­mals receiving pentobarbital, especially with chronic therapy.
Until this interaction is further clarified, it is suggested that li­docaine-induced seizures in dogs be treated initially with diazepam.
Forced alkaline diuresis is of little benefit for this drug.

Therefore, to interpret observations we have also attempted to distinguish changes in affinity from changes in pentobarbital efficacy.
The non-conducting conformation is rapidly reversible and is called 'blocked' to distinguish it from the desensitized state where no rebound current is observed and the recovery from the non-conducting state is far slower.

 SODIUM PENTOBARBITAL
In 2000 I became aware that the Food and Drug Administration, Center for Veterinary Medicine (FDA/CVM) had begun testing dry commercial dog food for levels of this drug.
Sodium pentobarbital is a drug, a barbiturate, which is used primarily to euthanize dogs and cats.
According to the FDA/CVM they had received reports from veterinarians "that pentobarbital, an anesthetizing agent used for dogs and other animals, seemed to be losing its effectiveness in dogs."

Barbiturates are used to relax patients before surgery, as anticonvulsants, and as sleeping pills.
Secobarbital (Seconal) and pentobarbital sodium (Nembutal) are short-acting barbiturates, amobarbital (Amytal) is intermediate in duration of action, and phenobarbital (Luminal) is a long-acting derivative.

 Pentobarbital
It is also used to reduce intracranial pressure and lower cerebral oxygen demand in patients with severe head trauma, Reye’s syndrome, or anoxic brain damage.
This produces blood concentrations ranging from 5000-112000 ng/mL (average 35000).

One potential problem with commercial pet food is pesticide residues, antibiotics, and molds contained in pet food ingredients.
