Hanging Tongue Syndrome in Dogs

Ever wonder why your dog’s tongue is lolling out of their mouth, even when they aren’t eating, grooming, panting, or giving kisses? 

While it’s often benign, this condition, known as hanging tongue syndrome (HTS), can be an indicator of several underlying health issues. Here is what you need to know about the causes of HTS, how to manage a chronically floppy tongue, and when to worry. 

What Is Hanging Tongue Syndrome (HTS)?

Hanging tongue syndrome occurs when a dog isn’t able to fully retract their tongue or keep it inside their mouth when at rest. This condition can be permanent or happen intermittently.

There are a number of possible explanations for HTS, so it’s important to rule out health problems before writing it off as quirky behavior. Here are a few likely underlying causes:

• Nerve damage or neurological problems
• Dental issues or missing teeth
• Malformations of the jawbone
• Trauma or injury to the mouth or jaw
• Genetics

Though it isn’t always a sign of a medical problem, if your dog’s hanging tongue is new or unusual, make an appointment with your vet. 

Breeds Prone to Hanging Tongue Syndrome

Brachycephalic (short nosed) breeds are more likely to experience HTS due to the shape of their jaws and the alignment of their teeth and tongue. Small breeds are also predisposed to hanging tongues as they age, largely due to the prevalence of dental disease and missing lower teeth. 

You’re more likely to see a lot of your dog’s tongue if you’re the pet parent of a:

• Bulldog
• Chihuahua
• Cavalier King Charles Spaniel
• Pug
• Boxer
• Pomeranian

What to Do About HTS

If hanging tongue syndrome is severe enough to interfere with your dog’s ability to eat or drink, your vet may recommend surgery. In the majority of cases, however, HTS will simply need to be managed. 

Because the tongue isn’t contained within the mouth, it can easily dry out, crack, or get infected if your pet becomes dehydrated. Check your dog’s tongue regularly for signs of irritation, and ensure they are able to drink plenty of water. 

Exposed tongues are vulnerable to extreme temperatures, and can even become frostbitten in cold weather. If you notice changes to the color or texture of your dog’s tongue, visit your vet right away. 

When to Worry About a Hanging Tongue

In many cases, hanging tongue syndrome won’t affect your dog’s overall health. However, if you suspect that your dog is in pain or their floppy tongue coincides with trauma, illness, or a new medication, don’t ignore it. 

Seek help if you notice:

• A cracked, bleeding, or irritated tongue
• Difficulty with eating or drinking
• Chronic bad breath or other signs of tooth decay
• Oral swelling or discoloration
• Unusual behavior

These symptoms could point to issues requiring medical intervention, such as infections or more serious neurological conditions.
