It can sometimes be difficult to differentiate between a fainting episode (syncope) and a seizure. Some dogs with severe, long-standing SSS can develop symptoms of congestive heart failure including weakness, labored breathing, and coughing. Fainting episodes (also known as syncopal episodes).Nonetheless, the appearance of SSS in a breeding dog should strongly discourage future breeding.ĭog with SSS becomes symptomatic because of their subnormal heart rate. The mode of inheritance is unknown, and there is no genetic testing available. Middle-aged to older females are particularly predisposed. Although any breed of dog can be affected, a genetic basis is suspect because SSS primarily affects Miniature Schnauzers, Dachshunds, Cocker Spaniels, West Highland White Terriers, and Pugs. The exact cause of the sinus node malfunction is unknown. ![]() Even with exercise or excitement, the heart rate remains at less than 40 beats per minute. Other dogs with SSS have a constant bradycardia (heart rate is too slow). In most cases, the sinus node will eventually resume its job in which case there will be periods of normal heart rate (60-100 beats per minute). Sometimes, an electrical impulse originating from another part of the heart will come to the rescue, particularly if the heart has stopped for several seconds. As a result, there are long pauses in between heartbeats. In dogs with SSS, the sinus node has lapses in which it discharges beats much too slowly, or not at all. The sinus node is responsible for electronically initiating the normal heartbeat and establishing the normal heart rate. Rather, it is a structure called the sinus node that is located within the heart. The sinus involved is not within the respiratory tract. You should also take your dog for regular veterinary checkups, so a medical professional can also listen for clinical signs of changes in the heart.Pay close attention all of you Miniature Schnauzer lovers! The breed you fancy is prone to a heart condition called Sick Sinus Syndrome (SSS). If you own or plan to adopt one of the breeds mentioned, you need to watch for symptoms they may exhibit that are common to heart disease. Signs include: weakness, exercise intolerance, collapse and fainting. As a result, dogs with this problem will be unable to maintain normal heart rates and many also suffer other changes in heart rhythm. In this disease, the heart’s electrical impulse-generating sites (called sinuses) fail to function normally. Sick sinus syndrome is a cardiac condition of unknown cause that affects the heart rate and rhythm of both humans and dogs. Sick Sinus Syndrome – often affects Miniature Schnauzers Signs include: Weakness, fainting spells, difficulty breathing, distension of the abdomen with fluid, and coughing are all possible in the later stages of disease. This condition is described as dilated cardiomyopathy (DCM). ![]() The pressure of the blood inside the heart causes these thin walls to stretch resulting in a much larger heart. As a result of this degeneration, the muscle becomes thinner, particularly the thick muscle wall of the left ventricle. But you can manage the effects of it with medication.ĭilated Cardiomyopathy – often affects large breeds such as Boxers and Dobermans.Ĭardiomyopathy is defined as degeneration of the heart muscle. Signs include: exercise intolerance, increased respiratory rate and/or effort, and coughing.īecause the condition is inherited, we can’t do much to prevent it. (Usually this valve closes when the heart contracts and the blood moves forward into the body.) With DMVD, a leaky mitral valve causes blood to go backward into the left atrium of the heart. Fifty percent of Cavaliers develop a heart murmur, indicating onset of the disease, by age 5, and nearly 100 percent by age 10. The incidence of degenerative mitral valve disease (DMVD) occurs more frequently in these breeds than any other. The two types of inherited heart disease veterinarians see most often in dogs are degenerative mitral valve disease (DMVD) and dilated cardiomyopathy (DCM).ĭegenerative Mitral Valve Disease – often affects small breeds such as Cavalier King Charles, Dachshunds, and Miniature and Toy Poodles. Heightened awareness gives your dog a better quality of life, increased quantity of life, and minimizes the need for additional medication. When the issue concerns the heart, you can slow down the disease before it progresses to heart failure. Knowing what health issues your dog is susceptible to gives you the chance to catch a malady early when you have ample time to modify it. ![]()
