The scare is overstated for dogs and real for other animals: the ASPCA says avocado's persin is primarily a problem for birds, rabbits, horses, donkeys and ruminants, where it causes cardiovascular damage. For dogs the practical hazards are the pit — a very common intestinal obstruction — and the fat content, which can trigger stomach upset or pancreatitis. Guacamole is worse than plain avocado because of the onion, garlic and salt in it.
Don't make it a habit. Watch for vomiting, diarrhea or a lost appetite over the next day and call your vet if it doesn't settle or your dog seems unwell.
