今すぐやるべきこと
- 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.
その背後の科学
アボカド（Persea americana）にはペルシンが含まれており、これは殺菌性脂肪酸誘導体です。犬は心臓損傷を引き起こす可能性がある鳥、ウサギ、馬と比較してペルシンに対して比較的耐性があります。犬では、ペルシンは軽度の胃腸刺激を引き起こします—嘔吐、下痢、腹痛。より大きな臨床的懸念は種であり、3-5cmの大きさで、特に20kg未満の犬で腸閉塞を引き起こす可能性があります。果肉の高い脂肪含有率（15-20%）も素因のある品種の膵炎リスクを増加させます（ASPCA、2023）。
有毒量計算機
摂取量: 果肉は低毒性—少量でも軽度の胃腸障害
LD50: LD50：ペルシンの正確なLD50は犬では不明；種の閉塞が主な臨床的懸念であり、全身毒性ではありません
その背後の科学: 出典：ASPCA動物毒物管理センター；Buoro et al.、1994
例：10kgの犬がアボカドの果肉を食べると通常は軽度の胃腸症状が出ます；3-5cmの種を飲み込むと小腸を閉塞する可能性があります。
症状のタイムライン：何を期待するか
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
よくある質問
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.
