The more you know …

We all know that greyhounds are a bit quirky when it comes to anesthesia. Let’s talk about it.

Hypothermia or lowering of body temperature: Greyhounds have a high surface-area-to-volume ratio, low body fat and thin hair, making them susceptible to losing body heat during anesthesia. This can be managed with warming blankets and temperature monitoring during the procedure and after.

Stress-induced hyperthermia: increased body temperature. Let’s face it. Our hounds can get a little nervous when exposed to new situations, which can cause stress and lead to a dangerous spike in body temperature (hyperthermia). Your vet will give your hound a medication prior to their procedure to take the edge off.

Anesthesia-associated hyperkalemia: This is a spike in potassium. Everyone needs potassium, even our hounds! Too little potassium (think dehydration) can cause weakness, cramping, fatigue and heart irregularities. Too much potassium, and the symptoms are basically the same, with an emphasis on heart irregularities. This is most often seen in longer procedures. Don’t be afraid to ask your vet if they are familiar with his condition. Not all of them are. Feel free to give them this information sheet.

Drug Metabolism: Greyhounds have a slower liver metabolism and lack enzymes to effectively process certain drugs, leading to prolonged recovery. Don’t hesitate to ask your vet what medication they use to make our hounds sleepy. Thiopental (a thiobarbiturate) should be avoided due to these metabolic differences.

The good news is your vet is most likely aware of the risks and will take appropriate steps to minimize them. Your partnership with your veterinarian will ultimately ensure your beloved hound’s safety.

Always moving forward,
