It can be concerning when you notice your dog licking the blood from your wound. Not only is a dog licking blood dangerous for the dog, but it can also be dangerous to you. However, there are a few reasons that dogs lick up blood when they see or smell it. We’ll give you six possible reasons your dog licks blood and answer a few common questions in the guide below.
The 6 Reasons Why Dogs Lick Blood
1. Instinct
It’s a dog’s instinct to lick its wounds. Most animals have the same instinct, so whether it’s you, the ground, another dog they get along with, or themselves when a dog smells blood, it’s normal for the dog to lick it.
Licking a wound is beneficial to dogs who live in the wild. After all, they can’t reach the first aid kit, so licking the wound is their way to promote healing, which we’ll discuss in the rest of the guide.
2. Speeds Healing (In Dogs)
When a dog is bleeding, the first thing they do is lick the wound because the licking speeds the healing for dogs. However, you should never let your dog lick your wounds, as it can lead to diseases and infections.
For the dog, it’s a way to speed up the healing time and clean the wound. However, it’s not the best way to speed up your healing time, so refrain from letting your dog lick your wounds.
3. Pain Relief (In Dogs)
Dogs also lick their wounds as a form of pain relief. The licking releases endorphins, which are a natural pain killer for dogs. The endorphins relieve the pain and make the dog happy, just as they do with humans.
Dogs are the same as humans in this regard. For example, when you hit your elbow on the doorframe, you automatically rub it to relieve the pain.
4. Predator Prevention (In Dogs)
In the wild, predators are attracted to the smell of blood. They will quickly attack weak, injured prey because they are easier to kill. Dogs lick away the blood so predators won’t be drawn to the smell. This is also why female dogs lick the blood away from where they give birth, to protect themselves and their puppies from predators. Predator prevention isn’t needed as much for domestic pets, but the instinct still remains.
5. Interested in the Smell of the Wound (In Humans)
Your dog may be interested in how your wound smells. It’s not necessarily the blood the dog is interested in; it could be the infection and odor the wound is giving off instead. The dog knows that you’re injured and is checking on your health.
6. Healing and Cleaning (In Humans)
As you already know, dogs can be very protective of their pet parents. Trying to lick your wound is the dog’s way of cleaning it, keeping you safe from predators, and helping the injury to heal. Though it is a very sweet and caring thing your dog is trying to do, it’s best not to let your dog lick your wounds, as it can make you and your dog sick.
