Your dog ate avocado. Take a deep breath—avocado toxicity in dogs is mild to moderate, and most dogs recover well with proper care. Here's what you need to do right now.
Is Avocado Dangerous?
The short answer: It depends on what part your dog ate and how much.
- Avocado flesh (the green part): Low toxicity. A small amount causes mild symptoms at worst.
- Avocado pit: High toxicity and blockage risk. This is the most dangerous part.
- Avocado leaves and stem: High toxicity. Concentrated source of persin (the toxic compound).
Avocado contains persin, a fungicidal compound that irritates the gastrointestinal tract in dogs. Humans tolerate persin well, but dogs are much more sensitive to it. The pit is the most concentrated source.
What to Do Right Now
Step 1: Assess what was eaten
- Did your dog eat the flesh, the pit, leaves, or the entire avocado?
- How much? (A lick, a mouthful, a whole fruit?)
- When? (Note the exact time—this matters for treatment decisions)
Step 2: Call your vet or animal poison control
- Call your vet immediately if:
- Your dog swallowed the pit (whole or in pieces)
- Your dog ate a large amount of avocado flesh
- Your dog ate leaves or stems
- You're uncertain about the amount or which part
- Call Animal Poison Information Service on 01202 509000 (24/7) for guidance
Step 3: Have this information ready when you call
- Your dog's weight and age
- What part of the avocado was eaten
- How much (estimate in grams or as a percentage of the fruit if possible)
- The exact time of ingestion
- Your dog's current symptoms (if any)
Step 4: Don't induce vomiting
- Don't make your dog vomit unless your vet specifically instructs you to
- This is especially important if a pit was swallowed—forcing vomiting could cause additional internal injury
Step 5: Monitor your dog closely
- Watch for symptoms (see "Symptoms to Watch For" below)
- Don't let your dog eat or drink for the next 1–2 hours while you assess severity
- Offer small amounts of water once symptoms are ruled out
If your dog ate only a small piece of avocado flesh (less than a tablespoon), toxicity risk is very low. You can likely monitor at home, but call your vet if any symptoms develop.
Symptoms to Watch For
Symptoms typically appear within 2–12 hours, but can take longer:
- Vomiting
- Diarrhoea (often watery)
- Loss of appetite
- Abdominal pain (restlessness, reluctance to move, whining, hunched posture)
- Lethargy or weakness
- Dizziness or incoordination (rare, indicates more serious toxicity)
- Difficulty breathing (if pit caused blockage or internal injury)
- Excessive drooling
If a pit was swallowed, additional symptoms include:
- Repeated vomiting (sign of blockage)
- Inability to eat or drink
- Severe abdominal pain
- Straining to defecate (constipation from blockage)
When to Seek Emergency Care
Go to the vet immediately (or emergency clinic if after hours) if your dog shows:
- Persistent or severe vomiting
- Bloody vomit or diarrhoea
- Severe abdominal pain
- Inability to eat or drink
- Difficulty breathing
- Signs of shock (collapse, pale gums, rapid weak pulse)
- Diarrhoea lasting more than 12 hours
If a pit was swallowed, your dog may need X-rays or ultrasound to check for blockage. Do not wait for symptoms—blockages can develop hours later and require emergency surgery.
What to Expect at the Vet
Your vet will:
- Examine your dog and ask about what was eaten, how much, and when
- Run blood work if there are concerns about systemic toxicity
- Take X-rays or ultrasound if a pit was swallowed, to check for blockage or internal injury
- Administer activated charcoal if caught very soon after ingestion (within 1–2 hours) and the vet thinks it will help
- Provide supportive care:
- IV fluids (if needed to prevent dehydration)
- Anti-nausea medication
- Monitoring over a few hours or overnight
- Soft food once your dog is stable
- Send you home with instructions for monitoring and care if the case is mild
Most avocado cases are managed with monitoring and supportive care. Surgery is only necessary if a blockage develops from the pit, which requires X-ray confirmation.
Prevention
Protect your dog from avocado:
- Keep avocados out of reach—on high shelves or in closed fridges
- Don't leave avocado pits unattended on counters or in the bin
- Secure your rubbish bin (dogs often scavenge for food waste)
- Never share avocado with your dog, even as a "healthy treat"
- Warn guests if they're eating avocado in your home not to leave it accessible
- Remove pits immediately after eating and dispose of them securely
- Watch your dog around other dogs' meals if avocado is being eaten
Avocado is not a necessary food for dogs. Safer alternatives for healthy fats include:
- Fish oil supplements
- Plain cooked chicken with skin
- Coconut oil (small amounts)
- Eggs
