Can Horses Drink Beer 2025: Vet‑Approved Insights & Best Practices

By Dr Duncan Houston BVSc 🩺

Beer has long been offered to horses—from racehorses sipping Guinness after a win, to carriage ponies enjoying a stout on hot days. But is it **safe or beneficial**? This comprehensive, vet-reviewed 2025 guide explores the science, risks, and best practices for giving horses beer. Let's separate myth from fact and help you make informed decisions for your horse. 🐴🍻

1. Why Some Horse Owners Give Beer

Anecdotal reasons include:

• Encouraging drinking during travel or illness by flavoring water with beer :contentReference[oaicite:3]{index=3}.
• Offering carbohydrates, B vitamins, and iron after exertion :contentReference[oaicite:4]{index=4}.
• Traditional remedy for anhidrosis—horses that struggle to sweat :contentReference[oaicite:5]{index=5}.

2. Can Horses Get Drunk?

Horses metabolize alcohol rapidly due to high levels of alcohol dehydrogenase in their liver :contentReference[oaicite:6]{index=6}. An average〝1200‑lb〟horse would need dozens of beers to feel intoxicated—about 20+ drinks at once :contentReference[oaicite:7]{index=7}.

3. Possible Benefits💡

• **Hydration tool**: Beer-flavored water may boost intake during travel or illness :contentReference[oaicite:8]{index=8}.
• **Anecdotal anhidrosis aid**: Some owners report restored sweating in “hot” horses :contentReference[oaicite:9]{index=9}.
• **Nutrient boost**: Contains carbs, B vitamins, iron—but commercial feeds often already provide these :contentReference[oaicite:10]{index=10}.

4. Risks & Considerations ⚠️

Despite traditions, consider these cautionary points:

• **Diuretic effect**: Alcohol can promote water loss—counterproductive in dehydration :contentReference[oaicite:11]{index=11}.
• **Liver strain**: Long-term exposure may be harmful to liver health :contentReference[oaicite:12]{index=12}.
• **Metabolic concerns**: High sugar/carb content may not suit insulin-resistant horses.
• **Additives**: Sulfites or preservatives may trigger allergies :contentReference[oaicite:13]{index=13}.
• **Regulatory issues**: Some performance organizations forbid beer and test results vary :contentReference[oaicite:14]{index=14}.

5. Recommendations for Safe Use ✅

If you choose to offer beer, follow these veterinary guidelines:

• Use **dark, stout beer** like Guinness—preferably unfiltered/unpasteurized for yeast and B‑vitamins :contentReference[oaicite:15]{index=15}.
• Limit to **one beer per day**, or a few times per week :contentReference[oaicite:16]{index=16}.
• Never exceed a beer per day; dose approximates **12‑16 oz per session**.
• Always provide **plain fresh water** alongside :contentReference[oaicite:17]{index=17}.
• Pour into a bucket or over feed—avoid glass :contentReference[oaicite:18]{index=18}.
• Monitor hydration, liver function, and reaction; discontinue if adverse signs appear.

6. Special Case: Anhidrosis Relief

Anhidrosis (failure to sweat) can lead to heatstroke. Though few controlled studies exist, many owners report improvement with a beer/day if prescribed by a vet :contentReference[oaicite:19]{index=19}. However, the environment and other factors complicate cause-and-effect. Always discuss with your vet first.

7. When to Avoid Beer

• **Sick or dehydrated horses**—seek professional advice before giving beer :contentReference[oaicite:20]{index=20}.
• **Pregnant, foaling, or aged horses** with liver or metabolic conditions.
• **Competition horses** unless confirmed legal by your governing body.
• Never use **flat beer for colic**—no research supports this :contentReference[oaicite:21]{index=21}.

8. Alternatives to Beer

If you're seeking hydration, nutrients, or sweating support, safer choices exist:

• Electrolyte supplements—balanced salt mixes for hydration.
• Pro-biotics and complete feeds for gut health.
• Environmental cooling strategies (fans, misting, shade).
• Veterinary interventions for anhidrosis (e.g. specialized supplements, treatments).

Final Thoughts 🍻

Beer isn’t essential to a horse’s diet—but used correctly, it can be a helpful tool for hydration, morale, or specialized cases like anhidrosis—always under vet supervision. Don’t let tradition override science. When in doubt, talk to your veterinarian, and consider safer alternatives like electrolytes and cooling strategies. Cheers to safe sipping—and healthier horses. 🐴
