Toxic Ingredients in Dog Food

❌ High protein (can cause kidney stress)
❌ Animal fats (indigestible for horses)
❌ Preservatives (BHA/BHT may be toxic)
❌ Garlic/onion powder (common in dog food, causes anemia)


Symptoms of Dog Food Poisoning in Horses

Within 6-12 hours, watch for:

  • Colic (pawing, rolling, restlessness)
  • Diarrhea or constipation
  • Lethargy or weakness
  • Elevated heart rate
  • Loss of appetite

🆘 Emergency: If your horse ate >1 cup of dog food, contact your vet immediately.


What to Do If Your Horse Eats Dog Food

Step 1: Assess the Amount

  • Small amounts (<1/2 cup): Monitor closely
  • Large amounts: Call vet ASAP

Step 2: Withhold Food (Temporarily)

  • Offer only water for 2-3 hours
  • Avoid hay/grain until vet advice

Step 3: Administer Activated Charcoal (If Advised)

  • Helps absorb toxins (only under vet guidance)

Step 4: Provide Probiotics

  • Restore healthy gut bacteria (e.g., Fast Track)

Veterinary Treatments

  • IV fluids (for dehydration)
  • Pain meds (if colic develops)
  • Blood tests (check kidney/liver function)

Prevention Tips

✅ Store dog food in sealed containers
✅ Feed dogs away from pastures/barns
✅ Use horse-proof latches on feed rooms


Final Verdict

While a few kibbles won’t be fatal, larger amounts can cause:
✔ Digestive upset
✔ Nutrient imbalances
✔ Toxicity (if garlic/onion present)

When in doubt, call your vet!
