Avocados – One of the healthiest fruits out there for us, and rightly so – they are delicious! Our fur babies’ bodies on the other hand don’t agree with out sentiments! Avocados contain a toxin called persin. While in small amounts, nothing too drastic will happen to your puppy, in larger amounts, it can lead to vomiting & diarrhea in dogs. So next time you dig into your oh so trendy avocado creations, keep it far away from your fur ball.
