Why Does a Dog Have Spots on Its Tongue?

Owners often worry when they notice spots on their dog's tongue. The mucous membranes create a favorable environment for bacteria to multiply, so even a small wound can become a gateway for pathogenic microorganisms.

Another type of disorder is a rash, which can also have various causes.

Causes of Spots on the Tongue

Spots can have different etiologies. Since the area is hidden, the owner may not notice the discoloration right away and might think it indicates some health problems in the pet. However, this is not always the case, as veterinary experience shows. They can be of both pathogenic (disease-related) nature and harmless.

Red Spots on the Tongue: Factors for Appearance

These include:

• burns;
• trauma;
• insect bites, such as from wasps.

It's important to distinguish spots from rashes. The former are pigmented areas. Small puppies often get injured while playing too hard with tough toys. Adult dogs can also be curious about wasps or bees. In these cases, there may be slight swelling and itching, along with clear signs of distress.

Burns can occur out of curiosity or from consuming food that is too hot. Wounds on mucous membranes heal quickly, but in the case of insect bites, it's important to monitor for anaphylactic shock.

It is extremely rare for a red spot on the mucous membrane to be a sign of canine distemper, as the tongue is not a typical location for this symptom.

White Spots and Coating on a Dog's Tongue

This color indicates pathogenic flora on the mucous membranes. Signs of diseases include:

• gastritis;
• leukemia;
• anemia;
• thrush;
• gastrointestinal issues;
• lung problems.

Due to the long list of potential causes, the actual reason is determined after examinations. Attention is paid to stool disturbances, unpleasant odors, elevated temperature, bloating, tremors, etc.

Dark Spots on the Tongue: Normal or Not?

They are considered normal if the puppy or dog shows no signs of distress. They are akin to birthmarks in humans. Breeds like shepherds, Great Danes, Newfoundlands, and even Labradors are predisposed to dark hidden markings. They are smooth, even, and not inflamed.

Why Did a Brown Spot Appear on the Tongue?

Just like in humans, dogs develop distinctive features as they grow. A light or dark spot on the tongue is acquired pigmentation, a mole, as mentioned earlier.

Oncological Risks

Throughout their lives, it’s important to pay attention to the number and structure of these spots. If an adult dog develops many pigmented, raised, and asymmetrical spots on the mucous membranes, it may indicate malignant neoplasms. Symptoms may include:

• pain;
• nausea, vomiting;
• weight loss;
• elevated temperature;
• loss of appetite;
• decreased activity, lethargy.

Dogs with previously sustained injuries to moles or spots are prone to cancer. Treating oncology in the early stages is possible through radiation or chemotherapy, so timely veterinary consultation is key to successful treatment.

Rash on a Dog's Tongue: Main Causes

Rashes differ from spots by their raised structure, usually containing fluid inside and accompanied by other symptoms: itching, swelling, discharge. Rashes on the tongue can vary in color and size depending on the pathogen:

• Red rash on the tongue. This is a manifestation of an allergic reaction, although it is not common. It is accompanied by tearing, sneezing, rashes on the body, and swelling. Antihistamines are used to alleviate symptoms.
• Red bumps on the tongue. Hypervitaminosis—an excess of vitamins in the body—can cause drying of the mucous membranes, leading to tearing, hair loss, and rashes on the body. Treatment: avoid excessive supplementation.
• White rash on the tongue. The cause is stomatitis. It consists of small pimples with fluid inside, arising from inadequate oral hygiene. The coating is removed, and the exposed areas are treated with antiseptics.

A more dangerous cause of pimples on the tongue is oncology. Malignant lesions consist of red hills with a bluish or gray tint. They merge into ulcers that do not heal. This is a rare pathology but causes high mortality.

A pink rash or small formations of the same color may indicate the papillomavirus. They are benign but can bleed and grow quickly if injured. Surgical removal or cauterization is indicated.
