Lymph nodes are also known as lymph glands, or just glands, and form part of the lymphatic system. They are tiny, bean-shaped clusters of cells found in groups or chains throughout the body. Lymph nodes are the most important component of the immune system and within these glands, lymphocytes (immune cells) exist. Glands consist of lymphatic tissue surrounded by a capsule of connective tissue and are located in the armpits, on either side of the neck, inside the chest, abdomen, pelvis and in the groin.
10 month puppy with heartworm. Species: Dog. Breed: Unknown; Terrier mix. Age: 6-12 months. I am considering adopting a 10 month old puppy from the SPCA and was told he was low positive for heartworm.
All puppies should have their initial veterinary exam by twelve weeks of age so the heart functions can be monitored. Most congenital heart defects can be detected at this early age with the aid of a stethoscope. Many heart defects cause abnormal heart sounds called murmurs. Murmurs are the result of turbulent or abnormal blood flow created by narrowed vessels, valves, or abnormal openings between heart chambers.
