What is Swelling of the Salivary Gland in Dogs? Salivary gland swelling in dogs, known as sialocele, occurs when one or more of the salivary glands located in the neck and jaw area leak saliva into the surrounding tissue. The leakage triggers the formation of a protective capsule called a sialocele to contain the saliva …
Myocarditis in Dogs Myocarditis in canines refers to the inflammation of the heart’s muscular wall, known as the myocardium. This inflammation is typically triggered by various infectious agents such as bacteria, viruses, rickettsiae, fungi, and protozoa. These agents can directly affect the heart or reach it from other parts of the body, leading to myocarditis. …
Sick Sinus Syndrome in Dogs Sick sinus syndrome (SSS) is a condition affecting the sinoatrial node (SA Node or SAN) in dogs, also known as the sinus node, which is responsible for initiating electrical impulses within the heart. These impulses prompt the heart to contract and beat rhythmically. SSS involves a disruption in the heart’s …
The spotlight on lead poisoning in pets has intensified due to the drinking water crisis in Flint, Michigan, a situation that veterinarians seldom encounter. In 2016, a group of dogs in Flint tested positive for lead exposure. Michigan State University’s College of Veterinary Medicine spearheaded a volunteer initiative to screen 300 dogs for lead in …
Hemangisaroma of the Heart in Dogs Hemangiosarcoma of the heart in dogs, where “hemangio” refers to blood vessels and “sarcoma” denotes an aggressive, malignant cancer originating from connective tissues, is a prevalent cardiac tumor among canines. This tumor typically emerges from the blood vessels lining the heart, either originating within the heart itself or metastasizing …
Left Anterior Fascicular Block in Dogs Left Anterior Fascicular Block (LAFB) in dogs is a cardiac issue arising from an irregular conduction system, which regulates the generation and propagation of electrical impulses across the heart muscles. These impulses trigger contractions essential for pumping blood throughout the body. When the conduction system malfunctions, it disrupts both …

What Are Syringomyelia (SM) and Chiari-Like Malformation (CM) in Dogs? Chiari-Like Malformation, also known as Caudal Occipital Malformation Syndrome (COMS) or occipital hypoplasia, is a relatively rare but debilitating neurological condition found in dogs. It leads to abnormal sensations, pain, and progressive weakness. Essentially, Chiari-Like Malformation occurs when a dog’s brain does not properly fit …

Atrioventricular Block, First Degree in Dogs First-degree atrioventricular block in dogs occurs when the electrical conduction from the atria to the ventricles experiences a delay or prolongation. Normally, the heart’s contraction is initiated by an electrical impulse originating from the sinoatrial node, which stimulates the atria. This impulse then travels to the atrioventricular node before …
Atrial Premature Complexes in Dogs A dog’s heart comprises four chambers: the two atria (singular: atrium) and the two ventricles. Normally, the heart maintains a highly synchronized rhythm between its various atrial and ventricular components, ensuring a consistent pattern of beats. Atrial premature complexes (APCs) disrupt this rhythm, causing the heart to beat prematurely, ahead …

Aortic Stenosis in Dogs Aortic stenosis denotes the narrowing of the aortic valve, which regulates blood flow from the left ventricle (one of the dog’s four heart chambers) to the aortic ventricular outflow tract. This constriction places undue strain on the heart, prompting heart muscle cells to enlarge to sustain forward blood flow and resulting …
