#8 – Avocados
You might want to hold off sharing that guac with your doggy pal. He'll thank you for it later.
What's In It:
Avocado leaves, pits, bark and fruit contain a toxin called persin.
What It Can Do:
Avocados can have toxic effects on dogs depending on the variety. They can cause upset stomachs in dogs, breathing difficulties, fluid buildup in the chest, but the most dangerous thing for them seem to the be the pit. Since it's slippery, the pit can accidentally be swallowed by dogs, leading to obstruction of the gastrointestinal tract.
