Assess Your Pet's Risk Right Now
| What Was Eaten | Any size | Risk Level | Action Required |
|---|---|---|---|
| Entire pit swallowed | Any size | HIGH | 🚨 Emergency vet NOW — obstruction risk |
| Flesh only (large amount) | < 20 lbs | Moderate | 📞 Call vet — pancreatitis/persin risk |
| Flesh only (small amount) | > 20 lbs | Low | 👀 Monitor for vomiting/diarrhea |
What to Do Right Now
- 1
Step 1: Determine What Was Ingested
Check if the pit was swallowed. The flesh alone causes mild GI upset, but the pit is a life-threatening obstruction hazard.
- 2
Step 2: Do NOT Induce Vomiting If Pit Was Swallowed
⚠️ If your dog ate the pit, do NOT induce vomiting — it can lodge in the esophagus on the way back up, causing worse obstruction.

Step 3: Watch for Guacamole Ingredients
If your dog ate guacamole, check the ingredients — onion, garlic, lime, and salt are additional toxins. Call ASPCA Poison Control at (888) 426-4435.

Step 4: Monitor for Symptoms
Watch for vomiting, diarrhea, abdominal pain, difficulty defecating (sign of obstruction), and lethargy. Symptoms usually appear within 2-12 hours.
The Science Behind It
Avocado (Persea americana) contains persin, a fungicidal fatty acid derivative. Dogs are relatively resistant to persin compared to birds, rabbits, and horses, which can suffer fatal heart damage. In dogs, persin causes mild gastrointestinal irritation — vomiting, diarrhea, and abdominal pain. The greater clinical concern is the pit, which measures 3-5 cm and can cause intestinal obstruction, particularly in dogs under 20kg. The high fat content of the flesh (15-20%) also increases pancreatitis risk in predisposed breeds (ASPCA, 2023).
Toxic Dose Calculator
Amount Eaten: Flesh low toxicity — mild GI upset at any amount
LD50: LD50: Persin exact LD50 unknown in dogs; pit obstruction is the primary clinical concern, not systemic toxicity
The Science Behind It: Source: ASPCA Animal Poison Control Center; Buoro et al., 1994
Example: A 10kg dog eating avocado flesh will usually have mild GI signs; a swallowed pit of 3-5 cm can obstruct the small intestine.
Symptom Timeline: What to Expect
Mild GI signs from flesh: vomiting, diarrhea, abdominal pain
Obstruction signs from pit: vomiting, straining to defecate, abdominal pain, lethargy
Risk window: untreated obstruction can progress to intestinal perforation or necrosis
Frequently Asked Questions
Are avocados toxic to dogs?
Avocado contains persin, a fungicidal toxin that is mildly toxic to dogs. The flesh causes mild GI upset in most dogs, but the pit (seed) poses a far greater danger as it can cause life-threatening intestinal obstruction. The skin and leaves also contain higher persin concentrations than the flesh.
What should I do if my dog ate an avocado pit?
If your dog swallowed an avocado pit, contact your vet immediately. The pit is large enough to cause intestinal blockage, especially in small and medium dogs. Do NOT induce vomiting — the pit can lodge in the esophagus on the way back up. Your vet will X-ray to locate the pit and determine if surgical removal is needed.
How much avocado is dangerous for dogs?
The flesh has low toxicity — most dogs experience only mild vomiting or diarrhea from eating avocado flesh. However, the pit is a choking hazard and obstruction risk regardless of amount. The leaves and skin contain higher persin levels and should be avoided. Pancreatitis risk increases with large amounts due to high fat content.
Can dogs eat guacamole?
No, guacamole is especially dangerous for dogs because it typically contains onion, garlic, lime juice, and salt — all of which are toxic to dogs. Onion and garlic cause hemolytic anemia, salt can cause ion poisoning, and lime peel contains essential oils. Call your vet immediately if your dog ate guacamole.
