You will find that most of the experts agree that avocado along with many other foods is considered to be poisonous for dogs and therefore should not be given to them. The fruit, leaves, seeds, and even the bark all contain toxic properties which are collectively known as “persin”, which is essentially what makes them poisonous for dogs and most other pets.
Dogs especially are sensitive to avocados so you should avoid giving it to them altogether. Feeding your dog avocado can lead to all sorts of adverse effects, including vomiting, diarrhea, gas, and upset stomach. Dog owners are advised never to give their pets any avocado because how toxic it is for them.
