Can Dogs Eat Liquorice?

We all want to treat our dogs to something new; however, the choices you make can genuinely impact your dog’s health and not to mention your bank balance. After all, our beloved dogs trust us to make the right decisions for them. If you love your dog, then researching it first is the best thing to do as a dog owner. There is no manual for bringing up dogs, and it’s generally what you can learn along the way and advice you can get from other dog owners that helps. So, let’s find out.

Dogs should not eat liquorice because it is toxic to their health. Liquorice contains no nutritional value and can cause diabetes, tooth decay, and obesity in dogs!

Why can’t dogs eat liquorice?

Dogs can not eat liquorice (black). It’s high in sugar that can cause tooth decay, diabetes, and obesity due to the high levels of sugar. It can also cause water retention, sodium retention and reduced potassium in your dog. However, it’s not just the amount of sugar that is highly unhealthy for your dog but also the main ingredient called glycyrrhizin. This will raise your dog’s blood pressure to dangerous levels resulting in death if eaten enough over long periods.

What’s in liquorice that is toxic to dogs?

  • Sugar
  • Glycyrrhizin
  • Xylitol (found in sugar-free liquorice)

Xylitol is an alternative to sugar

Sugar-free back liquorice means that the sugar is replaced with another ingredient. It is commonly replaced with a much worse component called Xylitol. Xylitol is very harmful to dogs, and just a tiny amount can kill your dog. It would be best if you never gave your dog anything sugar-free because all it means is that it’s been replaced with an artificial ingredient.
