What is CAC in dogs? - briefly
Canine Atopic Dermatitis (CAD) is an inflammatory skin condition caused by allergic reactions to substances such as pollen, dust mites, or mold. It is characterized by severe itching, leading dogs to excessively scratch, chew, and lick their paws and other affected areas, often resulting in hair loss and skin lesions.
What is CAC in dogs? - in detail
Canine Aortic Valve Stenosis (CAS) is a congenital heart condition that affects dogs, primarily affecting young and medium-sized breeds such as Boxers, Bulldogs, and Newfoundlands. The disease involves a narrowing of the aortic valve, which regulates blood flow from the left ventricle to the aorta. This constriction limits the amount of blood that can pass through, leading to increased pressure within the left ventricle. As a result, the heart must work harder to pump blood, which can cause hypertrophy or thickening of the heart muscle over time.
In severe cases, CAS can lead to significant health issues, including heart failure and sudden cardiac death. Symptoms often become apparent during exercise or periods of excitement, with affected dogs exhibiting signs such as fainting, weakness, and difficulty breathing. Early detection and intervention are crucial for managing the condition and improving the dog's quality of life.
Treatment options vary depending on the severity of the stenosis and the presence of clinical symptoms. In mild cases, veterinarians may recommend lifestyle modifications such as reduced exercise and stress management. For moderate to severe cases, balloon valvuloplasty is a common intervention where a catheter with a small balloon at its tip is inserted into the heart and inflated to widen the narrowed valve. This procedure aims to improve blood flow and reduce pressure on the left ventricle.
Regular follow-ups are essential for monitoring the dog's condition and adjusting treatment plans as needed. While CAS is a serious condition, proper management can help dogs lead active and fulfilling lives. Owners should work closely with their veterinarian to ensure optimal care and support for their pet.
