    Heart and Blood:

    The well known symptoms for enlarged heart in dogs are as follows: Lack of energy/depression: One of the most common symptoms where dog shows exercise intolerance due to poor heart function and inadequate blood supply Poor appetite: Due to inadequate blood flow and poor digestion. Weight loss. An enlarged heart in dogs (or Dilated Cardiomyopathy) is a serious condition which describes the expansion of the lower chambers of the heart (ventricles) or, less commonly, its upper chamber (atria). A dogТs heart will expand in this way when it is unable to properly contract and push blood out from it and to the rest of the body.

    An enlarged heart is the most common reason for heart failure jn dogs. The most commonly affected breeds are the large breeds such as Doberman pinschersIrish wolfhounds, Scottish Deer hound, boxer, and Afghan hound. The known causes of enlarged heart in dogs are not obvious every time.

    However, the most common causes are genetically related, due to a viral infection, or due to some nutritional deficiency. When the condition worsens, it results in heart failure and sadly, after a year or two, in the ih of your dog.

    Enlarged heart disease in dogs cannot be cured. However, it can be treated as per the diagnosed symptoms in dogs. In general, medicines are prescribed to treat the symptoms related to heart fnlarged. Drugs are prescribed to maintain proper blood pressure and ensure proper blood flow. Along with the medicines, proper care and rest is required to avoid heart failure.

    To help identify this condition of an enlarged heart, some of the signs and symptoms to watch out for include the dog showing signs of difficulty while breathing, coughing or hacking, a swollen or enlarged abdomen which will fill with fluid and then eventually collapse. There is no proper cure for a dog suffering from this particular condition.

    The main reasons for the occurrence of this condition are not really known. This particular condition is associated normally with taurine deficiencies. It is also associated with adriamycin deficiencies. The condition of enlarged heart in older dogs is a lot more common as compared to enlarged heart in puppies.

    Normally it is older, middle aged dogs that get affected and males more than females. An enlarged heart in small dogs is rarely observed. There are no obvious signs during the initial phase of this condition.

    Over a period of time this causess can culminate in the dog suffering from a heart failure. Usually, most of the symptoms are observed once the disease is how to cook pork loin chops boneless advanced. When dealing with an enlarged heart in dogs, treatment appears to be most successful with Cocker Spaniels, as they seem to respond to treatment a lot better.

    Normally dogs with an enlarged heart condition will have a shorter life expectancy. The enlarged heart in dog prognosis is usually about 6 months in Doberman breeds, from the time the condition is diagnosed. In dogs too, the heart comprises of four chambers.

    Normally a healthy dog will have a heart beat that ranges between 65 beats to about beats; this is the typical heart rate when at rest. Smaller puppies are seen to have exceedingly fast heart rates. These can range from to beats in a minute. Heart disease is generally common among dogs. Studies indicate that congenital heart disease among dogs occurs largely due to enlwrged factors. It is vital for all breeders of any dogs to ensure that they screen all dogs that that are likely to suffer from this condition starting from 6 weeks and continuing till about 8 weeks of age.

    When dealing with an enlarged heart in a dog the diet will always have to be a nutritious and extremely healthy. Junk food is likely to increase the chances of a dog suffering from heart disease. It is also heqrt to make sure that the dog gets adequate exercise. This can go what causes an enlarged heart in a dog long way to ensure that the dog stays healthy and fit.

Weakness and fainting: Due to weak hurt muscles, The hurt is unable to to contract fully and supply how to install reducer moulding properly. Swollen abdomen Ascites : Also known as edema, this is caused due to inadequate blood supply.

    The body releases certain hormones to compensate for the fluid deficiency. These fluids get deposited near the stomach and limbs, causing pain. Electrocardiogram ECG : Is a screening test to find out abnormal heart rhythm or arrhythmias.

    What is an enlarged heart in a dog?

    Aug 26, †Ј As with any heart condition, pets carrying excess weight (most commonly those fitting within the obese category) will be at a higher risk of developing enlarged heart in dogs. Apr 06, †Ј Dilated cardiomyopathy in dogs happens when the heart canТt properly contract, which leads to blood backing up in the heart chambers, causing the . Causes of Enlarged Canine Heart: In cardiac studies, an enlarged dog heart is specifically a stage of an underlying canine heart disease, which occurs due to congestion, inflammation or myopathies (muscular pathology) of the heart. A dog heart in this condition appears flabby and thinner, and eventually enlarged in size.

    I f your dog is having difficulty breathing, is losing weight and suffers from a cough, he may be suffering from the deadly condition of Dilated Cardiomyopathy DCM Ч also known as enlarged heart in dogs. But fear not, these symptoms could also be indicative of something less severe. Here is what you need to know about the condition, what the scientific evidence shows about DCM in dogs and what you should do if you suspect your dog to have it.

    The inflamed valves Ч unable to close properly Ч cause the blood to back up and flow back into the heart, thus causing a buildup of blood, filling and stretches out the heart walls and ultimately weakening the heart. Dogs with dilated cardiomyopathy have low survival rates. Let's take a look at the data. One study shows the average survival time of dogs with enlarged heart is anywhere from 6 months to 12 months, with very few cases where a dog survives 1. Another study with dogs and 38 breeds found survival rates of There are few outwardly visible symptoms of DCM in dogs that has been observed in clinical studies source , but if apparent those symptoms may include:.

    Most common sign is persistent coughing accompanied by difficulty breathing. A heart murmur is sometimes apparent and can be picked up with a stethoscope. As with any medical issue, we advise that you contact your veterinarian immediately. Unfortunately, the prognosis for a dog diagnosed with DCM is not great. The life expectancy for a dog with this condition can be from weeks to a few years Ч depending on the time of diagnosis, and treatment.

    An enlarged heart is a dangerous condition characterized by a heart that does not function properly due to inflammation. Along with being uncomfortable and distressing for the dog, it causes damage to all tissue within the body. This means that blood can flow backward through the partially open valves, the stress and pressure of which stretch out the heart walls, causing them to weaken over time.

    Not only will this cause damage to the heart itself, but as a direct result of the poor blood flow, all organs will be detrimentally affected, most notably the lungs. Any dogs suffering from heart disease will have the side effect of the body retaining more salt than necessary. In turn, this makes the body retain excess fluid.

    The result is fluid building up in the lungs, and as more and more fluid builds up, there is less space for oxygen. We most emphatically need to conduct more research to understand what causes enlarged heart in dogs. Unfortunately, while the affliction echoes the condition seen in humans , we know much more about what causes this in humans Ч most commonly, coronary artery disease. Research suggests that this is not the case for our four-legged friends. However, there are some key identifiers of who will be more susceptible.

    These risk factors include:. Research suggests that dogs most likely to develop DCM are those within the age range of four to ten years old, but that is most emphatically not to say that every senior dog will suffer from this horrible disease.

    Portuguese Water Dogs are an exception to this rule, most often showing signs at an incredibly young age. As with any heart condition, pets carrying excess weight most commonly those fitting within the obese category will be at a higher risk of developing enlarged heart in dogs.

    There's a good amount of scientific evidence showing that accurate body condition assessment of the dog and maintaining a healthy weight can prevent many health conditions and extend the dog's lifespan.

    After much confusion, and research later on, it was determined that a key factor was the change in diet. This was mostly due to WWII restrictions. Pets moved from natural meat to dry kibble, which ended in Taurine deficiencies. Experts believe that genetic susceptibility may play a role in determining canines that may be at high risk of contracting enlarged heart in dogs. Usually, veterinarians name breeds like the Doberman and Cocker Spaniels as well-known contract this condition at a greater rate than others.

    The same study also found that there's a gender predisposition, with male dogs being more likely to develop enlarged heart disease than female dogs. Nevertheless, there have been cases of enlarged heart in dogs that have been caught by astute owners and veterinarians. Some groups out there are encouraging pet owners to watch out for a few well-known signs of DCM in dogs.

    Normally, for enlarged heart in dogs, most common outwardly visible symptoms to keep an eye out for include:. As one of the most difficult diseases to diagnose , I have every sympathy for the unlucky vets who have the task of trying their utmost to spot it. Even the most qualified veterinarian, when checking for heart disease may be unable to detect DCM.

    This is because before the illness progresses to a severe state, the heart may in itself sound entirely healthy. The only true way to spot DCM is through an ultrasound. Imagine this scenario if you will. You bring your dog to the veterinarian for a check-up. Your dog is all signed off and ready to go. Or so the veterinarian would be led to believe. The fact of the matter is that we simply cannot tell whether the heart is inflamed solely from listening to it.

    Ultrasounds can be a costly affair, one which may require mild sedation. When researching cases of dogs working to beat the odds, I stumbled onto The Big Hearts Fund, a canine charity dedicated to raising funds and awareness for dogs and cats with heart disease.

    It was there that we found the story of Melanie the Chihuahua and her wondrous owner Martha. Not overly enthusiastic to take on a younger dog, Martha inadvertently fell in love with the young fluffball and gave her a forever home. I went from thinking this poor little puppy was going to be dead in a few weeks to the cardiologist telling me she now should have a normal life expectancy! It was here that the vet discovered something that no owner ever wants to hear Ч Melanie was suffering from an enlarged heart caused by patent ductus arteriosus a heart defect caused by problems during the development of the heart and had mere weeks to live.

    Luckily, in this case, surgery was available to correct the defect. As little is known to indicate what causes this medical conundrum, little can be known as to what will prevent it.

    There are some steps that you can take to help limit and detect this deadly disease. Some studies have tried many different medical and veterinary approaches to treat and prevent enlarged heart in dogs, with a varying degree of success source. This research was unable to pinpoint the best treatment and prevention for DCM in dogs. Dogs carrying excess weight are far more prone to heart disease, and for that matter, any disease. Recent studies on the digestive system of the canine have provided great insight into what constitutes an ideal diet, and the overall consensus is that a lean dog, fed with natural, minimally processed food will likely afford better health.

    None of us want to be in the position of having missed the window of opportunity to cure or treat our dog for a serious ailment. Our dogs truly are members of the family, and for that reason, I would encourage any self-respecting dog owner to conduct frequent at home check-ups, as well as attending regular check-ups at the vet's office too.

    With many options available for the committed owner to provide a better quality of life for their pooch during medical treatment. Research has shown PDF that, when discovered early on, an enlarged heart sufferer with immediate treatment can expect a far more favorable life expectancy.

    As mentioned earlier, heart disease of any kind will cause the body to retain too much salt. This is not good, mainly due to the fluid retention that it causes. You need to read treat packs and consider any human scraps before tossing them over to your four-legged friend as well. Obese dogs diagnosed with DCM will greatly benefit from losing weight through diet and exercise. The life expectancy and quality of life for dogs maintaining an overweight frame are often far shorter than their leaner counterparts.

    Of course, it's best to discuss any kind of natural supplements with your veterinarian before adding them to your dog's diet. Unfortunately, a diagnosis of DCM is never good news. The prognosis is guarded at best, but some medical treatments are available to slow the effects, and increase comfort levels.

    In cases where Cardio Dilatedmyopathy is apparent due in part to a malformation, surgical repair of the congenital disability can in many cases correct the DCM. In the later stages of the disease, breathing difficulties can cause distress and discomfort.

    By giving oxygen to the pooch in question, their quality of life will improve. One way that veterinarians attempt to relieve some of the fluid buildups is through the use of diuretics. Not a very fun procedure, Thoracentesis is the name of the procedure whereby a needle is used to relieve the fluid build up in the lungs by puncturing through the chest cavity.

    Taurine while necessary to a feline's diet, is not usually required as an additional supplement for canines. This is because a dog's body can produce it naturally. In rare cases, canines have shown a diminished ability in doing so and may need supplemental help.

    Knowing how to watch out for the signs of DCM in dogs and other heart conditions, and ensuring regular vet visits, is the best way to prevent this.

    A deadly disease, dilated cardiomyopathy combines the unfortunate difficulty in spotting, with the almost negligible treatment options available. For owners in the horrendous position of owning a dog diagnosed with this affliction, take solace knowing that your veterinarian is skilled and experienced in relieving pain and discomfort for your dog. In case of enlarged heart in dogs, by seeking immediate medical opinion and treatment when you suspect DCM Ч you're affording your dog a better quality of life for their last weeks, months, or even years.
