Unique Physiology: Tell Every Vet

Greyhounds have different "normal" bloodwork values and require special anesthesia protocols. Their low body fat (16% vs 35% in other dogs) affects drug metabolism. Always ensure your vet knows they're treating a sighthound.

The Greyhound Health Profile

Greyhounds are unique dogs with physiology built for speed. This affects everything from anesthesia to bloodwork interpretation:

  • Anesthesia sensitivity: Low body fat affects drug distribution and recovery
  • Unique bloodwork: Standard reference ranges don't apply
  • Cancer risk: Elevated osteosarcoma and hemangiosarcoma rates
  • Bloat risk: Deep chest predisposes to GDV

Major Health Considerations

1. Anesthesia & Drug Sensitivity

Critical awareness

Greyhounds metabolize drugs differently due to their low body fat (~16% vs ~35% in other breeds), different liver enzyme activity, and unique muscle composition. This isn't about being "fragile"—it's about using the right protocols.

Drugs Requiring Caution:

  • Thiopental (barbiturate) — prolonged recovery, avoid if possible
  • Propofol — use with care, slower metabolism
  • • Fat-soluble drugs stay in system longer
  • • NSAIDs may require dose adjustment

Safer Anesthesia Options:

  • Isoflurane or sevoflurane — preferred inhalants
  • • Propofol in reduced doses with careful monitoring
  • • Regional/local anesthesia when possible
  • • Extended monitoring during recovery

Why it matters:

  • • Low fat = less drug storage
  • • Different liver enzyme levels
  • • Higher muscle-to-fat ratio
  • • Longer recovery times common

What to do:

  • Always tell vet it's a Greyhound
  • • Ask about sighthound protocols
  • • Request extended recovery monitoring
  • • Consider sighthound-experienced vet

2. Unique Bloodwork Values

Don't misdiagnose!

Greyhounds have genetically different "normal" bloodwork values. Using standard canine reference ranges will flag healthy Greyhounds as abnormal. This can lead to unnecessary worry, testing, or even inappropriate treatment.

ParameterStandard DogGreyhound Normal
Hematocrit (PCV)37-55%50-65%
Red Blood Cells5.5-8.5 M/µL7.4-9.0 M/µL
Platelets175-500 K/µL80-200 K/µL
White Blood Cells5.5-16.9 K/µL3.5-6.5 K/µL
Creatinine0.5-1.8 mg/dL0.8-2.4 mg/dL
T4 (Thyroid)1.0-4.0 µg/dL0.5-1.5 µg/dL

Why This Matters:

A healthy Greyhound with platelets of 120,000 could be misdiagnosed as having a bleeding disorder. A Greyhound with T4 of 0.8 could be incorrectly put on thyroid medication. Always ensure Greyhound-specific ranges are used.

3. Cancer Risk

Elevated risk

Like many large breeds, Greyhounds have elevated rates of certain cancers, particularly osteosarcoma (bone cancer) and hemangiosarcoma (blood vessel cancer).

Osteosarcoma signs:

  • • Limping that doesn't improve
  • • Swelling on leg bones
  • • Pain when touching limbs
  • • Decreased activity
  • • Usually affects long bones

Hemangiosarcoma signs:

  • • Sudden weakness/collapse
  • • Pale gums
  • • Distended abdomen
  • • Unexplained weight loss
  • • Often affects spleen/heart

4. Bloat (GDV)

Life-threatening

Greyhounds' deep chests put them at risk for gastric dilatation-volvulus (bloat), where the stomach fills with gas and can twist. This is always an emergency.

Emergency Signs (Act Immediately!):

  • • Unproductive retching (trying to vomit, nothing comes up)
  • • Distended/hard abdomen
  • • Restlessness, pacing, can't get comfortable
  • • Drooling excessively
  • • Rapid breathing, weakness

Prevention:

  • • Feed 2-3 smaller meals daily
  • • No exercise 1 hour before/after eating
  • • Use slow-feeder bowls
  • • Avoid elevated food bowls
  • • Consider prophylactic gastropexy

Risk factors:

  • • Deep, narrow chest (Greyhound body)
  • • Eating too fast
  • • One large meal daily
  • • Stress or anxiety
  • • Family history

5. Temperature Sensitivity

Low body fat

With their thin coats and low body fat, Greyhounds are sensitive to both heat and cold. They need protection in extreme temperatures.

Cold weather:

  • • Coats/sweaters essential
  • • Limit time outside in cold
  • • Watch for shivering
  • • Provide warm bedding

Hot weather:

  • • Risk of overheating during exercise
  • • Avoid midday activity
  • • Provide shade and water
  • • Watch for heat exhaustion

Essential Care for Greyhounds

Priority Health Steps

Always identify as Greyhound
To every vet, every visit
Request sighthound bloodwork ranges
Don't accept standard ranges
Ask about anesthesia protocol
Before any procedure
Know bloat emergency signs
Minutes matter with GDV

Retired Racing Greyhounds

If you've adopted a retired racer, they may have additional considerations:

  • • Dental disease is common (racing dogs often have minimal dental care)
  • • Tick-borne diseases should be screened (Ehrlichia, Babesia common in FL dogs)
  • • May need time to adjust to home life, stairs, glass doors
  • • Corns on feet are common—watch for limping

Emergency Signs:

  • Unproductive retching or distended abdomen (bloat)
  • Sudden collapse or pale gums
  • Prolonged recovery from anesthesia (over 4-6 hours)
  • Limping with swelling on limbs
  • Severe weakness or inability to stand

Frequently Asked Questions

What is the lifespan of a Greyhound?

Greyhounds typically live 10-14 years. They have unique physiology affecting anesthesia and bloodwork. Always use a vet familiar with sighthounds for procedures.

Why is anesthesia different for Greyhounds?

Greyhounds have very low body fat (16% vs 35% in other dogs), affecting how anesthetic drugs are distributed and metabolized. They're sensitive to barbiturates and may need longer recovery monitoring.

Why do Greyhounds have different bloodwork values?

Greyhounds naturally have higher RBC/hematocrit, lower platelets, lower WBC, lower T4, and higher creatinine. These are NORMAL for the breed. Standard ranges will flag healthy Greyhounds as abnormal.

What is normal platelet count for a Greyhound?

Normal Greyhound platelets are 80,000-200,000/µL (standard range is 175,000-500,000/µL). A Greyhound with 120,000 platelets is healthy, not thrombocytopenic.

Are Greyhounds prone to cancer?

Yes, they have elevated rates of osteosarcoma (bone cancer) and hemangiosarcoma. Watch for limping that doesn't improve, swelling on legs, and unexplained lethargy.

Are Greyhounds prone to bloat?

Yes, their deep chest increases GDV risk. Feed smaller, frequent meals, avoid exercise around mealtimes, and know the signs: unproductive retching, distended abdomen, restlessness.
