Dilated cardiomyopathy is often a progressive condition and there is no cure. Treatment is aimed at lengthening your treasured companion`s life and making your pet as comfortable as possible.
Sadly, the life expectancy in most cases of enlarged heart in dogs is poor. Your vet will advise you on your dog`s expected prognosis, taking into account the progression of the disease at the time of diagnosis. Generally, the life expectancy is from six to 24 months.
In general, dogs that are diagnosed with congestive heart failure can live anywhere from 6 months to 1 1/2 to 2 years. Other factors that affect how long a dog can live with CHF include: The age of the dog. The severity of their condition.
Shih Tzu are prone to multiple types of heart disease, which can occur both early and later in life. We`ll listen for heart murmurs and abnormal heart rhythms when we examine your pet.
The three most common causes of an enlarged heart in dogs are pericardial effusion, dilated cardiomyopathy, and valvular heart disease.
Depending on the condition, an enlarged heart may be temporary or permanent. Treatment for an enlarged heart may include medications, medical procedures or surgery.
Treatment of DCM in Dogs

The most common medications prescribed in patients with DCM and congestive heart failure include: ACE inhibitors, like enalapril or benazepril, which work to expand the veins leaving the heart and reduce resistance so that it is easier for the heart to pump blood back out to the body.

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 1.5 years (source). Another study with 189 dogs and 38 breeds found survival rates of 17.5% at one year and 7.5% at two years, which is very low (source).
Short walks are tolerated by most dogs with mild to moderate heart disease, but excessive activity can worsen heart failure or trigger irregular heart rhythms.
Stage 4: During this final stage of congestive heart failure, your dog`s breathing will become difficult even when they are resting. Fluid will likely begin to accumulate in various parts of your pup`s body, leading to swollen legs or abdomen, which will make walking difficult and may lead to vomiting.
Dilated cardiomyopathy may have a sudden onset of clinical signs; however, the disease has actually been developing slowly and subtly. Some dogs may develop severe congestive heart failure (CHF) in only a few hours. Rapid, heavy breathing, a blue tongue, excessive drooling, or collapse may be the first signs.
Short-lived stressors can trigger bouts of vomiting, diarrhea, or changes in behavior and eating patterns, and chronic stress is known to increase the chances of developing serious and sometimes lifelong disorders, such as heart disease and diabetes.
Certain types of grain-free dog food seem to be involved, FDA says. Dogs fed “grain free” food based on peas, lentils or potatoes are developing an unusual condition that can cause an enlarged heart, the Food and Drug Administration warned Thursday.
The mainstays of a good low-sodium diet may be fresh beef, pork, chicken, bland macaroni and/or low-sodium. Do not give “dog snacks.” A good diet is 1/4-pound ground round or other lean beef, 2 cups cooked white rice without salt, add a tablespoon vegetable oil, and one tablet of Pet-Cal supplement.
An enlarged heart isn`t a condition in itself, but a symptom of an underlying problem that is causing the heart to work harder than normal. Some of the many causes include coronary heart disease, idiopathic dilated cardiomyopathy, high blood pressure and heart valve disease.
Depending on the cause of the enlarged heart, it may or may not be reversible. Over time, an enlarged heart can cause serious health problems. Most notably, it can increase the risk of sudden death.
“It depends on the etiology,” or origin of the problem. With certain conditions, such as congestive heart failure, complete reversal of the enlargement of the heart may not be possible. But with other conditions, such as pregnancy or a treatable infection, a complete reversal of the condition may be possible.
Vetmedin is a medication that has been prescribed by your vet to treat your dog`s heart disease. Vetmedin tablets are also used to treat dogs with asymptomatic MVD; when given to dogs with an enlarged heart, Vetmedin delays the onset of heart failure and increases overall survival time.
Full recovery may take 6-12 weeks. Your physician will tell you when you may be physically active again, including going back to work or resuming sexual activity.
“The most common clinical sign of congestive heart failure is persistent coughing accompanied by difficulty breathing.” Many dogs with CHF will tire out more easily, have reduced stamina, and do not engage in playing or walking as they once did.
The severity of the heart murmur dictates how much exercise is okay for your dog. For low-grade heart murmurs, exercise can continue as normal. For high-grade heart murmurs and dogs with congestive heart failure, gentle short walks only are advised.
As a rule of thumb, dogs with heart conditions should not travel by air, experts in Taoyuan said.
Prognosis. Dogs with hemangiosarcoma in the right atrium have a survival time that ranges from 0 to 229 days (average = 56 days). For dogs with heart-based tumors, a retrospective study showed that the survival time ranged from 0 to 1,096 days (with an average of 213 days).
However, in general, with the appropriate medications and recheck appointments, many dogs with heart failure due to DCM live for more than six-12 months.

Q. How do I determine how much my overweight pet should weigh?
ANSWER : A. There are many tools to determine overweight and obesity levels in pets. A new tool, morphometric measurements and body fat index, are available to accurately determine a pet’s ideal weight; this will allow an accurate determination of the amount of food a pet should receive to achieve weight loss. Feeding the correct amount will lead to greater weight loss success.

There are many weight loss food options to help pets reach their ideal weight. Your veterinarian can help make a ideal weight recommendation. Here are some tips to help your dog lose weight in a healthy and safe way:

1. Diet: Providing a healthy and well balanced diet is essential to your pet’s overall health. Finding the right food for your dog can be a challenging process. For those overweight animals many commercial dog companies offer weight loss diets, but it is important to evaluate food labels for adequate nutritional content.

You want to ensure you are not missing other essential vitamin or mineral content. Volume of food is also important and the amount of food that works for one breed of dog may not be the same for another breed of dog. Portion control as opposed to free-choice feeding can help your dog to drop a few unnecessary pounds.

There are also prescription weight loss foods designed by veterinary nutritionists, such as Hill’s r/d (http://bit.ly/1AoENSd). Some pet owners find that home cooking is the best option for helping to provide a well-balanced and realistic diet plan. There are websites such as balanceit.com that offers recipes to fit your dog’s specific needs. Consulting with your veterinarian or a veterinary nutritionist to find the appropriate diet is a great way to help your dog be as healthy as possible.

2. Exercise: Another great tactic for weight loss for your dog is exercise. Whether this is through running, walking or playing with a favorite toy all of these are wonderful types of exercise to help keep your dog at a lean and healthy weight.

For those pet owners with busy schedules utilizing professional dog walking services or playtime through dog daycare services is another option. It has been shown that those pet owners that exercise regularly with their pets generally live a healthier lifestyle.

3. Physical therapy: As animals age pet owners offer encounter their favorite canine having more difficulty walking and have a dwindling desire to play with toys. Physical therapy, specifically hydrotherapy is a wonderful way to help older and arthritic animals gain more mobility and lose weight. Hydrotherapy has been proven to have several therapeutic effects on the body including, muscle strengthening, relief of swelling, decreased joint pain, less stiffness in limbs, improved circulation, weight loss, and increased tissue healing to name a few.

4. Veterinary visit and blood work: Weight gain can also be related to underlying health concerns such as hypothyroidism or other endocrine disorders. Scheduling a veterinary evaluation and routine blood work can be another important component in increasing the longevity of your dog’s life. Conditions such as hypothyroidism that predispose dogs to gain weight can be treated with a daily medication to improve hormonal balance. If feel that your dog is unnecessarily overweight there can be an underlying health condition that needs to be addressed.

5. Healthy treats: Pet owners love the chance to reward their favorite canine companion with treats and most dogs jump at the chance to consume these delicious products. The problem is many treats, which can include commercial dog treats or table scrapes can add many unnecessary calories to your dog’s daily intake. Reading labels and making note of the calories in these treats is an important component of understanding your dog’s overall health. Treats should not exceed more than 10 percent of your pet’s daily calories. There are healthier treats that can be offered to your pet to keep calories lower yet provide a fuller sensation. A pet owner can add steamed or pureed vegetables, such as carrots, green beans or sweet potato to add more fiber and thus a fuller feeling for your dog.

Q. I have a 10 year old mutt who is hyper but doesn’t like hyper dogs. Getting another dog from a shelter soon any ideas on calm breeds?
ANSWER : A. If your dog is uncomfortable with other dogs (of any sort), it is important that you bring your current dog to the shelter so he can meet the dog you plan to adopt. You should check out your local shelter, and walk around looking at all of the dogs. Mixed breeds have mixed amounts of energy and it’s tough to recommend a breed. I suppose I would say calm breeds would be the Great Pyrenees, the Newfoundland, the Bernese Mountain dog CAN be a calm breed.. really with any breed you will have mixed litters. Many breeders breed specifically the “calm” Newfies, or the “hyper” Bernese. If you are going to adopt from a shelter however, it’s impossible to expect that level of breeding.

As I said, just be sure you bring your dog along so you can slowly introduce the dogs. If your dog is uncomfortable, immediately separate them, and try again in a couple of minutes. You don’t want to force them to get along, and you don’t want to move too quickly when introducing them.

Q. Whenever I take my dog on walks he always barks at people and others dogs in my neighborhood. What should I do to resolve the problem
ANSWER : A. The very first thing to do is to make sure your dog is getting sufficient physical and mental exercise every day. A tired dog is a good, happy dog and one who is less likely to bark from boredom or frustration. Depending on his breed, age, and health, your dog may require several long walks as well as a good game of chasing the ball and playing with some interactive toys.

Figure out what he gets out of barking and remove it. Don’t give your dog the opportunity to continue the barking behavior.

Ignore your dog’s barking for as long as it takes him to stop. That means don’t give him attention at all while he’s barking. Your attention only rewards him for being noisy. Don’t talk to, don’t touch, or even look at him. When he finally quiets, even to take a breath, reward him with a treat. To be successful with this method, you must wait as long as it takes for him to stop barking. Yelling at him is the equivalent of barking with him.

Get your dog accustomed to whatever causes him to bark. Start with whatever makes him bark at a distance. It must be far enough away that he doesn’t bark when he sees it. Feed him lots of good treats. Move the stimulus a little closer (perhaps as little as a few inches or a few feet to start) and feed treats. If the stimulus moves out of sight, stop giving your dog treats. You want your dog to learn that the appearance of the stimulus leads to good things.

Teach your dog the ‘quiet’ command. Oddly, the first step is to teach your dog to bark on command. Give your dog the command to “speak,” wait for him to bark two or three times, and then stick a tasty treat in front of his nose. When he stops barking to sniff the treat, praise him and give him the treat. Repeat until he starts barking as soon as you say “speak.” Once your dog can reliably bark on command, teach him the “quiet” command. In a calm environment with no distractions, tell him to “speak.” When he starts barking, say “quiet” and stick a treat in front of his nose. Praise him for being quiet and give him the treat.

As in all training, always end training on a good note, even if it is just for obeying something very simple, like the ‘sit’ command. If you dog regresses in training, go back to the last thing he did successfully and reinforce that before moving on again. Keep sessions short, 15-20 minutes max, and do this several times a day.

Q. My dog keep hacking like a cough or something in her throat, what can I do?
ANSWER : A. Hacking and coughing can be caused by a number of things ranging from foreign bodies such as twigs stuck in the mouth or throat, to infections or illnesses such as Bordetella or Kennel cough, common in dogs that frequent kennels, dog daycare or dog parks. In older dogs, heart and lung issues can also be indicated by a cough that does not go away.

If you think there may be a foreign object stuck in your dog’s throat, you can sweep a finger gently through the back of the mouth or throat if your dog will let you. If something feels stuck and is not easily moved by the finger, it is best to contact your vet to have the object safely removed. This usually requires sedation so that your dog does not become panicked or move, causing the object to become further stuck or cut the throat.

If your dog is showing other symptoms of illness in addition to the cough such as runny nose or eyes, fever, lethargy or changes in appetite, it may indicate a viral or bacterial illness such as kennel cough. These are usually treated with a cough medication in severe cases, plus rest and treatment of any additional symptoms until the condition improves. In bacterial causes, antibiotics may also be given to help your dog feel better.

If your dog has a constant cough that does not go away, or has had changes in ability to exercise, breathing, or appears to have swelling around the chest or abdomen, in may indicate a lung or heart issue. Your vet can thoroughly examine your dog for any signs of heart or lung problems and can then offer care as needed depending on the cause.

Q. Which common foods are poisonous to pets?
ANSWER : A. That’s a great question. As responsible pet owners we need to be aware of food items that can be harmful to our canine or feline companions. Here are some of the most common foods proven to cause illness in our animals at home:

Chocolate: A favorite and irresistible treat amongst most humans, chocolate is considered toxic to dogs. In very small amounts it is usually not a huge issue, but with larger volumes and with darker chocolates pet owners should be concerned. Chocolate contains methylxanthine theobromine, which is similar to caffeine. Chocolate ingestion can cause vomiting, diarrhea, hyperactivity, issues with normal heartbeats, seizures, and in some severe cases, death. It is best to keep your favorite chocolate treats in a good hiding spot and out of reach of your dog or cat.

Grapes and raisins: Dogs should not consume grapes and raisins because of the risk of acute kidney failure. Most dogs experiencing grape or raisin toxicity will begin to have vomiting and/or diarrhea within 6-12 hours of ingestion. Other abnormal clinical signs include lethargy, abdominal pain, dehydration, and tremors. Kidney failure develops within 24-72 hours of the initial ingestion. There are some dogs that do not experience these devastating side effects. It is best to contact your veterinarian or veterinary emergency facility if you believe your pet has ingested grapes or raisins.

Garlic and onions: We often forget that our meals contain these two popular ingredients and will allow our furry companions a few bites or licks. Onion and garlic both can cause a type of poisoning that results in damage to red blood cells, making them more likely to rupture. They can also cause stomach upset and mouth irritation. Look for pale gums, increased breathing or drooling or any vomiting or diarrhea.

Bread dough: Unbaked bread dough is considered poisonous to our pets. The bread dough, when ingested, expands in the stomach because of the warm and moist environment. This can lead to a bloated or even twisted stomach. In addition yeast is often added to our baking products to help get bread to rise, and when this yeast is fermented it produces both carbon dioxide and alcohol. The alcohol produced can be absorbed into the bloodstream and causes dangerous drops in blood sugar, blood pressure and body temperature. Common clinical signs include vomiting or retching, distension of the stomach, weakness and collapse.

Macadamia nuts: Ingestion of these nuts are not proven to be fatal in dogs but can cause them to experience uncomfortable clinical sings, including fever, joint stiffness, vomiting, tremors and difficulty walking, especially in their hind legs. Often your pet will start to feel better after about 48 hours, but supportive veterinary care (such as pain medication) may help ease their discomfort.

Xylitol: The most common ingredient used in sugar-free gum is xylitol, which is a non-caloric sweetener. It is also found in some oral rinses, toothpastes and vitamins. Xylitol and dogs do not mix – it can cause a dangerous drop in blood sugars levels. Dogs will often display signs of disorientation, black tarry stool, tremors and seizures. If severe enough some dogs have developed liver failure. Keep your gum away from your canine companion.

Avocados: Avocados are not actually poisonous to dogs or cats but as many veterinarians can tell you the avocado pits can cause a foreign body obstruction. Avocados contain persin, which is actually toxic to the majority of pet birds. The abnormal clinical signs associated with avocado ingestion in birds include, respiratory distress, inability to perch, liver and kidney failure and sudden death.

Go forth and enjoy your favorite foods, but keep in mind which foods you should avoid sharing with your furry family members. Whenever in doubt, contact your veterinarian for healthy and safe food suggestions.

Q. Why do dogs eat grass?
ANSWER : A. Some pet parents get concerned when they see their favorite canine nibbling on grass in the yard. They wonder whether it is because hunger, boredom or an indication of an underlying illness. Often the consumption of grass will result in vomiting because it irritates the stomach and gastrointestinal tract. This is an extremely common problem for dog parents. There is no one reason for why dogs exhibit these behaviors and it is very much dependent on each dog. Here are some of the reasons why our dogs choose to eat grass:

1. Nutritional Issues

Historically speaking, dogs are considered omnivores, which mean they consume a variety of both meat and plant-based food. There is some indication that dogs with a low fiber diet may choose to scavenge in the grass to fulfill this nutritional deficiency. These dogs may also find that grass has an appealing flavor and consistency. If you feel that this may be the reason for your beloved canine consuming grass then consider discussing with your veterinarian on how to incorporate more fiber into your dog’s diet.

2. Boredom

Many dogs who are not receiving adequate exercise will be become bored and search out activities to occupy their time, including eating grass. Evaluate how much exercise your dog is getting on a daily basis and consider more walks or other fun activities, such as playing fetch or tug of war.

3. Upset Stomach

There is a belief that dogs with an upset or gassy stomach will self-medicate by consuming grass. Vomiting often follows this grass eating activity eliminating the contents of the stomach or changing the gas distension within the gastrointestinal tract. However, there is not much scientific evidence to back up this theory. If you are concerned about too much gastric acid in your dog’s stomach or any other underlying medical issue that could be the reason for their grass eating, consult with your veterinarian.

Overall, grass eating is usually not toxic to your dogs unless your lawn contains chemicals, including pesticides or herbicides. Monitor your dog’s behavior along with his diet and exercise to determine if there is a reason for the inappropriate grass snacking.

Q. Looking to get a second dog to go along with my 10 year old dog. He doesn’t like other hyper dogs, are there any specific “calm” dog breeds?
ANSWER : A. Stay away from puppies then. No matter what breed u get, they will be hyper. Calmer breeds can include something like a climber spaniel (dog that the cartoon droopy was modeled after) Basset hounds (although you give up hyper and they are very loud) it’s hard to say on a lot of breeds due to the fact that not all dogs are the same even in the same breed. Research almost any breed that appeals to you if your going to buy a pure breed dog, if going to rescue or adopt from a pound then go look around and see the attitude of the different dogs and see how they do with your pet.
