Causes of Swelling on a Dog's Neck: Possible Reasons

The Possible Causes of Swelling on a Dog's Neck

1. Poor Absorption of Injected Medication. If you notice a lump on your dog's neck, it might be helpful to recall if your furry friend has recently been vaccinated or received any injections. Swelling can occur if the medication wasn't absorbed properly, leading to lumps or bumps under the skin. If the lump is near the injection site, it's likely due to this issue. Rest assured, this is usually not a cause for concern, as the lump should dissipate within a few days as the medication is absorbed. If absorption is slow, you can apply a warm compress to speed up the process. In some cases, improper disinfection or incorrect injection technique might also lead to swelling due to severe allergic reactions at the injection site.

2. Exudation from Salivary Glands. Dogs have numerous lymph nodes around their neck, as well as salivary glands like the parotid, sublingual, and submandibular glands, which secrete fluids. If these glands become infected or are physically irritated, the fluid can渗漏 into the muscle or subcutaneous tissue, forming soft lumps. While this usually doesn't affect the dog's appetite, severe cases can impact breathing and require immediate medical attention. If glandular exudation is suspected, a veterinarian may use ultrasound or Xrays to identify the cause and location of the exudation.

3. Neck Collision. Accidental collisions with sharp objects during play or vigorous activity can cause a dog's neck to bump, potentially piercing the capillaries of an artery. This can lead to bleeding, which the dog's muscle tissue will encapsulate to form a cyst. Cysts typically resolve on their own, with some cases clearing up in as little as 710 days, while others may take 12 months. If a cyst persists, a minor surgical procedure may be necessary to remove it and prevent potential malignancy.

4. Insect Bites. If your dog's neck lump is accompanied by redness, itching, and persistent scratching, it might be due to insect bites. In such cases, applying an antibacterial and antifungal ointment can help alleviate the itching and promote healing.

5. Subcutaneous Lipoma. Subcutaneous lipomas present as solitary, slowgrowing, spherical lumps beneath the skin. These lumps can be benign or malignant. If you suspect your dog has a lipoma, it's best to consult a veterinarian for diagnosis. Benign tumors tend to grow slowly, whereas malignant tumors may rapidly expand and even ulcerate. If a lipoma grows quickly, it's advisable to have it surgically removed to prevent secondary complications.

The above outlines the common reasons for swelling on a dog's neck. When you notice a lump, observe for any other abnormalities and take targeted treatment measures based on the situation.
