Are Crayons Toxic to Dogs?

 Crayons are a beloved childhood tool for artistic expression, known for their vibrant colors and ease of use. However, for those who share their lives with furry friends, concerns about the potential toxicity of crayons to dogs may arise. It is natural for pet owners to prioritize their dog’s health and safety, so it is essential to understand the risks associated with specific substances. Read below to explore the question, “Are crayons toxic to dogs?” and what to do if your dog eats them. 

What Can Happen If Your Dog Eats Crayons? 

Dogs are natural explorers and scavengers, often getting their paws on anything they find interesting or appealing. This includes household items like crayons, which might catch their attention due to their vibrant colors and waxy texture. While a dog chowing down on a crayon might seem harmless or comical, it is important to be aware of the potential risks and consequences. 

Crayons are typically made of non-toxic materials, and most brands claim to be safe if accidentally ingested by humans or pets. Therefore, if your dog snacks on a crayon, you might initially feel relieved knowing it’s unlikely to be toxic. However, this doesn’t mean there are no risks involved. Your dog can experience dangers such as intestinal obstruction. If your pup is suffering from persistent vomiting, a decreased appetite, or abdominal pain, additional care may be needed. 

Adverse Effects of Ingesting Crayons 

If your dog consumes crayons, they are at risk of stomach upset or potential intestinal blockage. Potential signs and symptoms include: 

  • Vomiting 
  • Excessive drooling 
  • Decreased appetite 
  • Abdominal pain 
  • Constipation 


If your pup develops symptoms after consuming one or several crayons, please contact your veterinarian and Pet Poison Helpline at (855) 764-7661. To avoid a crayon incident with your dog, ensure that the crayons are put away when not in use. It’s advised to follow best practice by keeping your dog out of the room when they are being used so they cannot eat them if you happen to look away.
