Why does my dog turn pink at night?

Have you ever noticed your dog’s coat turning pink at night? You may have thought Why does my dog turn pink at night? it was just a trick of the light? but it turns out there’s a reason for this strange phenomenon. It all has to do with a type of pigment called porphyrin. 

This pigment is found in the cells of many animals, including dogs. When exposed to light, porphyrin becomes fluorescent and glows pink. So why does this happen? Well, it’s speculated that porphyrin may help animals see in low-light conditions. 

It’s also possible that the pink glow helps animals communicate with each other. Whatever the reason, it’s clear that this strange quirk is just another example of how fascinating our furry friends can be!


What causes pink coloration in dogs?

The pink coloration in dogs is caused by a build-up of bilirubin in the blood. Bilirubin is a yellow pigment that is produced when red blood cells break down. 

When there is an excess of bilirubin in the blood, it can build up and cause the skin and mucous membranes to turn yellow or orange. In some cases, the build-up of bilirubin can cause the skin to turn pink or red.


Is it harmful?

There is no definitive answer to this question since there is no scientific evidence to support any claims. Some people believe that pink coloration is caused by a reaction to light, while others think it could be due to a build-up of pigment in the skin. 

There are also those who believe that it is simply a trick of the eye and that the dog’s coat actually looks normal during the day.


How can you treat it?

If your dog turns pink at night, it is likely suffering from a condition called erythrocytosis. This condition causes the body to produce too many red blood cells, which can lead to anemia. 

Treatment for erythrocytosis will vary depending on the severity of the condition but may include blood transfusions, medications, and/or dietary changes. 

If you think your dog may be suffering from erythrocytosis, it is important to bring them to the vet as soon as possible for treatment.


Are there any home remedies?

There are many home remedies for dogs that turn pink at night. Some home remedies include adding a little bit of vinegar to their water or using a mild soap on their coat. 

You can also try using a pet-safe flea and tick shampoo on your dog’s coat. If your dog is still turning pink after trying these home remedies, it is best to consult with your veterinarian.


Prevention tips

if your dog is healthy and you’re simply looking to prevent their skin from turning pink at night, there are a few things you can do. 

  1. make sure they are not spending too much time in the sun during the day. If they are outside, provide them with plenty of shade and water so they don’t overheat. 
  2. consider using a pet-safe sunscreen if your dog will be spending extended periods of time in the sun or if they have a lighter coat that doesn’t offer much protection. 
  3. keep an eye on any changes in your dog’s diet or environment that could be causing their skin to react differently. If you recently switched their food, introduced a new product into their grooming routine, or moved to a new home, these could all be potential causes of pink skin. 
  4. consult with your veterinarian if you have any concerns about your dog’s health or if their skin turns pink more frequently or for longer periods of time than usual.


When to see the vet

If your dog is turning pink at night, it’s important to see the vet right away. There are a few possible causes of this symptom, and only a veterinarian will be able to give you a definitive diagnosis.

One possible cause of pink skin in dogs is an allergic reaction. If your dog has been exposed to something new that could be causing an allergic reaction, such as a new food or medication, the vet will be able to confirm whether or not this is the cause.

Another possible cause of pink skin in dogs is a condition called pemphigus foliaceous. This is a rare autoimmune disease that can cause the skin to blister and peel. If your dog has any other symptoms in addition to the pink skin, such as hair loss or sores, this may be the diagnosis.


Your veterinarian will likely recommend some diagnostic tests, such as blood work and biopsies, to confirm the diagnosis and rule out other possible causes. Once a diagnosis is made, the vet will develop a treatment plan that is specific to your dog’s needs.



It’s normal for a dog to have some color changes in their fur, and there are a few reasons why your dog might turn pink at night. 

It could be due to the temperature change between day and night, or it could be an allergic reaction to something in their environment. If you’re concerned about your dog’s pink fur, talk to your vet to rule out any other potential causes.
