Additional tests or procedures may be necessary to help diagnose the lump on your dog's neck, so be prepared for a thorough examination.

An enlarged thyroid gland can be a possible cause of a noticeable lump on a dog's neck, although it's not extremely common in dogs.

The thyroid gland is located in the neck and regulates metabolism by releasing hormones.

Enlargement of this gland may be palpable and visibly present as a lump.

Goiter, a goiter refers to an enlarged thyroid gland and can result from various conditions, including iodine deficiency, inflammation, or tumors.

Thyroid tumors are another possibility and are more common in older dogs.

A swollen lymph gland on a dog's neck can be an indication that the immune system is fighting an infection or disease. Symptoms may include lumps or bumps on the neck, swelling or inflammation of the neck, pain or discomfort when touched, loss of appetite, lethargy or weakness, and fever. In some cases, it may be a sign of a more serious condition, such as lymphoma.

Lumps on a dog's neck can be caused by a sting or bite from an insect or spider, leading to redness, swelling, and itching.

Insects like bees, wasps, and ants can cause a reaction in dogs, resulting in lumps or bumps on their skin.

Removing the stinger if it's still in the skin is essential to treat the lump, which can be done by gently scraping the area with a credit card or other flat object.

Applying a cold compress can help reduce swelling and alleviate discomfort.

A lump caused by a sting or bite can be rinsed with water and a mild shampoo to help soothe the skin.

If the lump is large or painful, a veterinarian may prescribe medication to manage the symptoms.

Blood vessel tumors can be a type of growth that forms from the blood vessels in the neck.

These tumors can be benign or malignant and can develop in any part of the body that contains blood vessels.

Hemangiomas are the most common type of benign blood vessel tumor found in dogs, typically presenting as small, red, raised lumps that are soft to the touch.

They are often found on the skin or just under the skin and may bleed if they are irritated or injured.

Hemangiopericytomas are a type of malignant blood vessel tumor that can occur in the neck, usually firm and difficult to move when touched.

They may cause pain or discomfort and can grow quickly, often requiring treatment with surgery, radiation therapy, or a combination of both.

These tumors are most commonly found in older dogs, although they can occur in dogs of any age. They can be difficult to diagnose, as they can be mistaken for other types of tumors or skin conditions.

A biopsy is usually required to confirm the diagnosis of smooth muscle tumors of the skin. They are typically small and firm, and can be either solitary or multiple.

Smooth muscle tumors of the skin can occur anywhere on the body, but are usually located on the trunk or limbs.

A swollen lymph gland on your dog's neck can be a concerning sight, but it's essential to understand what it might mean. Lymph nodes are small, bean-shaped structures that are part of the immune system, and research shows that swollen lymph glands can be caused by infections, inflammation, or cancer.

The symptoms of a swollen lymph gland on a dog's neck may include lumps or bumps on the neck, swelling or inflammation of the neck, pain or discomfort when touched, loss of appetite, lethargy or weakness, and fever.

Swollen lymph nodes can be found in many different areas of your dog's body, including lumps on their neck under their jaw or a lump in their armpit. Enlarged lymph nodes can mean anything from your dog fighting a small infection to canine lymphoma developing in that area.

Here are some common places to find an enlarged lymph node on your dog:

If you suspect the lump on your dog's neck is a swollen lymph node, report it to your dog's veterinarian as soon as possible. Noticing that there is a lymph node that is swelling, getting them to the vet quickly will greatly improve their chances for easy treatment.

An abscess is a pocket of pus that forms under the skin, often caused by bites, scratches, or foreign objects.

Painful abscesses can cause swelling, redness, and warmth around the lump, making them hard to ignore. They can rupture on their own or need to be lanced by a veterinarian.

A cyst, on the other hand, is a fluid-filled, painless sac that can form under the skin, often caused by blocked oil glands, infections, or injuries.

Cysts can vary in size and may feel firm or soft to the touch, but they're usually not a cause for concern. If your dog has a painful lump, it's likely an abscess, but if it's painless, it might be a cyst.

Foreign bodies, like puncture wounds from fights or thorns, can cause abscesses to form, which can become infected and painful.

Your veterinarian will prescribe antibiotics to fight the infection and may need to lance the abscess to drain the pus.

A hematoma is a raised bruise on your dog's skin, typically caused by direct trauma to that area.

It can be painful when touched for your dog, so be gentle when handling them.

A hematoma isn't necessarily a cause for concern, but it's a good idea to have it checked out by a vet to ensure there aren't any hidden injuries, like a broken bone, beneath the bump.

The vet can assess the situation and provide guidance on the best course of action.

A foreign body isn't always needed to form an abscess, and it will continue to grow until it ruptures on its own or a veterinarian lances it.

A sebaceous cyst is a blocked oil gland on your dog, similar to a pimple, and it can be small or grow significantly larger.

Do not try to pop a cyst on your dog, as it can become irritated or infected and pose a threat to their health.

Sebaceous cysts will often go away on their own by shrinking away or popping in their own time and releasing a white, pasty substance.

Fatty growths, also known as lipomas, are a common condition in older dogs.

They are actually benign tumors of fat cells that can appear as a lump under the skin.

Most lipomas are found on the chest or abdomen.

A fine needle aspiration is the best way to determine if a lump is a lipoma.

This procedure gives a clear answer and should be done by a vet before assuming it's a lipoma.

Lipomas usually don't need treatment, but may be removed if they occur in difficult positions like the legs or armpits.

Younger dogs may also need their lipomas removed if they will grow significantly in a normal lifespan.

Warts can look terrible, but the good news is that they should go away on their own after a few months.
