If you have a dog, you might worry about what could happen if they accidentally taste human blood.
It might sound scary, but you don’t need to be too scared – the outcomes aren’t always as bad as you might imagine.
Some people think that if a dog comes into contact with human blood, it will always lead to something really bad happening.
However, that’s not always true.
Usually, a dog can taste and smell human blood without any big problems.
But in certain situations, different things can happen – some not so bad, and others more serious.
In this article, I’ll take a closer look at what goes on when a dog comes into contact with human blood.
I’ll talk about what might happen to the dog, like changes in behavior, and how you can stop these situations from happening.
Lastly, I’ll give you advice on what to do if your pet reacts in some way after tasting or smelling human blood.
What is the Natural Instinct of the Dog?
When a dog encounters human blood, it’s important to know that the dog’s natural way of thinking is to safeguard things it thinks are important.
Some dogs have been bred to be especially good at guarding or herding. This means that your dog might act aggressively if it senses human blood.
Dogs are born with behaviors like biting and chewing to explore their surroundings.
So, if your dog smells or tastes human blood, it might want to explore more, which could lead to being aggressive.
It’s crucial to keep your dog on a leash or in a closed area when you’re near other people.
Also, avoid leaving food or objects around that might catch your pet’s interest.
It’s crucial to keep in mind that you can teach and control a dog’s natural behaviors through good training and consistent rules.
This involves making sure there’s enough space between the dog and other people and stopping the dog from biting or chewing things at home.
If the dog reacts, it’s best to keep those reactions as small as possible by watching closely and acting quickly.
With proper care, your pet can develop good habits without much delay.
Possible Health Issues from Consuming Human Blood
Many people worry about what could happen if a dog tries human blood.
It’s true that drinking human blood can put people at risk for infections like hepatitis C, B, and HIV.
So, it’s crucial to understand the possible dangers if a dog swallows human blood.
Especially, we need to pay attention to the chance of kids who have drunk human blood getting too much iron.
Having too much iron can make kids very sick, causing them to vomit a lot, have diarrhea, feel stomach pain, get dehydrated, and even pass away.
And not just in kids – adults can also have problems from having too much iron, like issues with the liver, lungs, heart, and diabetes.
So, it’s really important to get quick medical help and tell your doctor if your dog has tasted or eaten any human blood, even if it’s just a little bit.
Acting fast can stop any health problems or lasting harm from happening because of the dog eating human blood.
What to Do if Your Dog Tastes Human Blood
If a dog bites you and you can safely keep it under control, the right thing to do is to quickly get in touch with your local animal control authorities.
Many experts believe that dogs that have tasted human blood shouldn’t be left around in public because they can be risky.
The good news is that a dog won’t start liking the taste of human blood if it tries it once.
So, you don’t have to worry about that.
But being around human blood might make the dog act more aggressively, which is why it’s really important to handle the situation correctly when it happens.
Usually, the only option remaining is to euthanize the animal in a kind way.
Most of these accidents could be prevented or made less serious with good training and careful watching during situations that might be risky.
This might be tough for pet owners to agree with or understand.
Things to Avoid When a Dog Encounters Human Blood
If your dog tries human blood, there are important things you must never try to do. You should never:
- Give the dog-human blood from a transfusion.
- Give the dog blood from a different animal for a transfusion.
- Give the dog blood from an old or expired source.
By being careful with these steps, you can keep your furry friend safe from serious health problems.
Giving a dog the wrong kind of transfusion can lead to really bad outcomes like sepsis, anemia, or even death.
So, it’s better to be cautious and ask trained experts when you need to make medical choices.
Possible Changes in Behavior after a Dog Tastes Human Blood

It’s important to know that dogs don’t develop a liking for human blood, just in case you’re worried about what could happen if your dog tries it.
The taste of blood usually happens because of different reasons, and it might show there are hidden health issues or biological reasons behind it.
However, dogs might show some different behaviors after eating human blood. These could involve:
- They might become overly active or excited, leading to lots of barking and jumping around.
- They could start eating things that aren’t food, like dirt, grass, or other non-edible objects.
- Your dog might get annoyed or show aggression in specific situations.
- They could feel anxious when they’re in new places or around new things.
Keep in mind that after a dog tries human blood, their behavior might not easily go back to normal, and it could get worse if not handled right.
If your dog shows any of these behaviors after coming into contact with human blood, it’s crucial to reach out to your vet for expert guidance as soon as you can.
How to Keep Dogs and Humans from Being Exposed Again
To prevent situations where your pet might touch human blood, it’s important to take some steps.
Pet owners should get their dogs vaccinated for rabies, just in case there’s an accidental scratch or bite from another pet.
It’s also really important to give your dog regular medicine that stops heartworms. This can help keep your dog from getting sick from viruses or bacteria.
Also, if you’re around a pet that has touched human blood, be sure to wash your hands really well after you touch them.
This will stop more exposure and keep infections from spreading.
Lastly, if you think your pet has eaten someone else’s blood, it’s best to take them to the vet quickly to prevent health problems in the future.
Conclusion
To wrap up, if a dog comes into contact with human blood, it’s important to know about the possible risks.
Depending on how serious it is, it might be a good idea to get advice from a professional vet to make sure the dog doesn’t get any infections.
Also, to keep the pet safe and healthy, it’s smart to get them preventive treatments like vaccinations.
And don’t forget, it’s really crucial to provide a safe and comfortable place for your pet to prevent them from getting hurt.
By doing these things, pet owners can make sure their dog stays safe and happy.
