The 10 Most Common Causes of Pet Poisoning

You know it’s important to keep your pet away from hazardous things, but do you know what the most common causes of pet poisoning are? While most people know that chocolate is bad for dogs (and cats!), other poisonous items are less well known. To help raise awareness and help prevent tragedy, the Pet Poison Helpline has published a list of the 10 most common dog and cat poisons of the past year. Some of those (like chocolate!) won’t surprise you, while others, like essential oils or lilies, may.  Take a look at the lists (one for dogs and one for cats) below. Remember, some of the items are more toxic than others, but all have the potential to do significant harm to your pet.
