Have you noticed a peculiar swelling on your dog's neck or jaw? It could be more than just a bump; it could be a sign of salivary gland tumor, a condition that demands immediate veterinary attention.
Salivary gland tumors, though uncommon, pose a significant health risk to our canine companions. These abnormal growths develop within the salivary tissues and can manifest in various forms, with adenocarcinoma being the most prevalent and aggressive type in dogs. Understanding the nature of these tumors, their symptoms, and available treatment options is crucial for responsible dog owners.
