Protect Your Pup: 10 Early Signs of Heart Failure in Dogs

Find out on the general signs of heart failure in dogs which are associated with this condition such as rapid breathing, coughing, exhaustion and build-up of fluids in the lungs. Understand when a problem arises and how to prevent the situation from drastically changing for the worse with good management.

Congestive heart failure in dogs is a severely worded condition that points to the last phase of chronic canine heart disease, which means that the circulatory system requires the heart to pump sufficient blood for the body. Understanding when a dog is beginning to present clinical signs consistent with end-stage heart failure is important to ensure adequate healthcare and treatment and quality of life decisions are made.

Heart failure in dogs

It is a clinical condition where the dog’s heart cannot pump blood fast enough to keep up with the body’s needs. This can occur due to any form of heart disease and leads to low blood fluidity to the organs & tissues, thus eliciting symptoms & complications. There are several key aspects to understanding signs of heart failure in dogs: There are several key aspects to understanding heart failure in dogs:

Types of Heart Failure in dogs

1. Left-Sided Heart Failure:

Primarily, the left side of the heart is unable to pump blood that is supposed to circulate in the lungs hence causing fluid to build up in the lungs known as pulmonary edema. Some of the signs include coughing, shortness of breath, and exercise-induced aggravation.

2. Right-Sided Heart Failure:

In these cases, the right side of the heart cannot pump blood approximately and it leads to effusions in the abdomen (ascites), liver congestion or peripheral edema. They involve abdominal distension, breathlessness and aspects of fluid retention.

3. Congestive Heart Failure (CHF):

CHF is a disease that impairs the function of both atria of the heart, causing swelling of body tissues and the accumulation of fluids in the lungs, abdomen, and limbs. CHF in dogs has several causes which are described below;

Chronic Valvular Disease (CVD):

There are several diseases that can lead to congestive heart failure in dogs; however, it is most frequently seen in dogs with a body weight ranging between 15 and 55 pounds. The data dissolve the valves of the heart, the mitral valve in particular because it thickens and gets unable to shut properly. CVD results to blood back flow (regurgitation) – heart enlargement—failure apart from pulmonary embolism.

Dilated Cardiomyopathy (DCM):

This sickness is more prevalent in large breed and has features where there is dilatation of the Heart Muscle through weakening thus making the ability of the Heart to pump blood minimally. It unfortunately has been seen that DCM can progress to congestive heart failure.

Congenital Heart Defects:

These heart defects are congenital: PDA or VSD, and they are distinguished by their presence at birth. Neglected situation accompanied by these structural abnormalities, may lead to heart failure.

Heartworm Disease:

This is a disease that is occasioned by parasitic worm which resides in the heart and the arteries that spread to the lungs. It also results in heart failure since it seriously affects the heart and lungs ranked low.

Pericardial Disease:

It involves some structures and organs around the heart, for example; pericardial which include pericardial effusion is a fluid buildup on the sac that surrounds the heart. It can constrict blood vessels, particularly the arterioles which wrap around the heart and decreases it capability of pumping blood as effectively as it used to do.

Signs of Heart failure in dogs

Following are the some signs of heart failure in dogs:

Severe Respiratory Distress

• Labored Breathing: This symptom usually entails tachypnea, or heightened respiration, and the utilization of the abdominal compartment for breath. Other signs may include orthopnea, which is when the dog would stand or sit with the legs spread out apart or when they would sit with the elbows spread out in order to have an easier time breathing.
• Panting: This panting may be accompanied with the tongue hanging out and lack of motivation to lie down due to problem breathing that worsens when the fluids exert pressure on the lungs.
• Coughing: This can be even more manifested at any instance when the dog is moving or is just plain lying. Typically it presents as a dry, non-productive cough like a gagging or hacking cough and occasionally the patient may cough up frothy, bloody sputum if the pulmonary edema is advanced.

Extreme Fatigue and Weakness

• Lethargy: The dog may sleep all day, or show no signs of defocusing and ignore what is happening around. Disparate actions, for instance, arising from the bed to drink water or walking to the balustrade to pee turns into a chore.
• Weakness: Muscle atrophy can also develop from neglect or lack of activity in the muscles over a period of time or reduced physical exercise. Some of the signs that may indicate that one needs a wheelchair include lagging, TRYING to trip, basically staggering and even having a problem in standing up.
• Exercise Intolerance: This is characterized by the dog slowing down during walks, unwilling to budge ahead, or suddenly dropping on the floor because of tiredness.

Fluid Accumulation (Congestive Symptoms)

• Ascites: The presence of fluid may cause discomfort which may shift to the abdomen, there may be a decrease in appetite and vomiting due to pressure exerted on the stomach by the swollen abdomen.
• Edema: The presence of swollen limbs causes discomfort and pain on the affected limbs or part of the body. In the extreme, these areas may become scaly, red, or even develop sores and infections due to weak skin cover above the affected areas.
• Pleural Effusion: The presence of this fluid means that there is need for thoracentesis or removal of the fluid putting pressure on the lungs for breathing. Commonly, this procedure is done with the help of a veterinarian but can also be done by any person with knowledge of carrying out the procedure.

Gastrointestinal Symptoms

• Loss of Appetite: Anorexia is present at this time because the body starts to channel blood away from the gastrointestinal tract. Other measures may include providing specialty foods or using medications as appetite builders.
• Nausea and Vomiting: This can be tackled through antinausea that are recommended by a vet medicinal officer. Dividing the food portions in a day and taking them frequently also helps in this regard as well as avoiding high-fiber foods.
• Diarrhea: For chronic diarrhea, it may be required for the patient and the medical practitioner to seek dietary changes and medication to ensure that the patient is adequately hydrated and properly absorbing nutrients.

Changes in Behavior

• Restlessness: A dog may experience discomfort and therefore pace, circle, or often assume a standing position by getting up and down. They might even whine or bark excessively than usual is well, or at least more often than usual, depending on the extent of the stress.
• Isolation: This is mostly exhibited by the dog staking around in a bid to establish a comfortable area free from intrusions to lay down and rest. It also gives a comfortable, quiet zone that would ease the tension from a hectic day’s work.
• Depression: In some cases, the dog looks less inclined to engage in activities the dog once loved for instance playing, welcoming its owners or going for walks.

Abnormal Heart Sounds

• Heart Murmur: Its pitch and site can help veterinarians assess the type and severity of the heart problem. Regular monitoring is essential.
• Arrhythmias: More frequent and severe palpitations can be accompanied by other symptoms such as syncope or cardiopulmonary arrest. Treatments sometimes involve taking medications for these arrhythmias, still, there are.

Syncope (Fainting)

• Fainting Episodes: These episodes occur due to a condition referred to as hypotensive and /or low cardiac output state. They can be quite short, although occasionally they can be disconcerting. It is essential for the dog and for the people, especially the children, to remain calm and avoid stressing the dog further.

Cyanosis

• Blue or Pale Gums: This is an early indicator of hypoxia, which is a condition that characterized by low oxygen levels in the body. This calls for veterinary intervention, and if observed, the animal needs to be taken to the vet since its respiratory or circulation systems may be fatally compromised.

Cold Extremities

• Cold Paws and Ears: This is a sign of the compromised circulation of blood on the outer part of the body. Blankets can be useful as well as taking measures to warm the living area where a dog is placed, however, it is a sign of the dramatic progression of the disease.

Decreased Urine Output

• Oliguria: This may prompt concern of kidney involvement because of low cardiac output. Another important aspect that should not be overlooked is specialization in observing the amounts of fluid that are ingested and excreted. At times, diuretics also prove helpful but have to be administered cautiously as they could increase the depletion of water.

Diagnosis of Heart Failure in dogs

• Auscultation: Using a stethoscope to check for any abnormal heart or lung sounds by listening to the heart beat and its rhythm.
• X-rays (Radiographs): To see how big the heart is or if there is any build-up of fluid in the lungs or abdomen.
• Echocardiogram (Ultrasound): For the purpose of understanding the anatomical structures and the function of the heart.
• Electrocardiogram (ECG): To monitor the heart’s pumping action and to diagnose the presence of abnormal heart rhythms or arrhythmias.
• Blood Tests: To look for associated diseases and to determine function of different internal organs.

Treatment for Heart Failure in Dogs

Management of heart failure in dogs is a broad concept with major objectives consisting of alleviation of clinical signs, enhancement of clinical status, and halting of pathophysiological changes.

1. Medications

Diuretics:

• Furosemide (Lasix): Typically employed in the elimination of invasive fluids within the lungs and in other body tissues. This prevents the buildup of dangerous levels of fluids since it promotes the formation of urine.
• Spironolactone: A potassium-sparing diuretic which separates substantial amount of fluid without effecting potassium loss.
• Thiazides: Another diuretics which are used in some circumstances to treat fluid retention which is also called oedema.

ACE Inhibitors (Angiotensin-Converting Enzyme Inhibitors):

• Enalapril (Enacard): It aids in the relaxation of the blood vessels, thus reducing the amount of work the heart has to do and consequently lowering the person’s blood pressure.
• Benazepril (Lotensin): Like enalapril it helps in regulation of blood pressure and is useful in the functioning of the heart.

Beta-Blockers:

• Atenolol: Applied in managing heart rate and decreasing arrhythmias through eliminating adrenaline’s impact within the heart.
• Carvedilol: Used in the management of heart failure due to its action of reducing heart rate and enhancing Heart’s performance.

Positive Inotropes:

• Pimobendan (Vetmedin): Strengthening of contractions of the heart and dilation of blood vessels lead to overall betterment of the condition of the heart function and blood flow.

Vasodilators:

• Hydralazine: This medication widens blood vessels, reducing the effort required by the heart to pump blood through the arteries.
• Nitroglycerin: Applied externally to assist in the reduction of force and regulation of blood flow.

Antiarrhythmics:

• Sotalol: Assist in managing the arrhythmias and ensuring that the h eat has a normal straight beat.
• Amiodarone: Prior to their use, they were usually applied to patients with narrows complex tachycardias.

Antitussives:

• Butorphanol: Applied as a cough suppressant in circumstances where chronic cough is not easily relieved such as in patients with chronic bronchitis or cough secondary to heart failure.

2. Dietary Management

Low-Sodium Diet:

• Reducing the amount of salt consumed helps prevent fluid retention. There are diets created for young dogs that are prone to developing heart disease or dogs that already have the condition.

Balanced Nutrition:

• It is well-established that superior diets entail six family groups in proportionate quantities. Added to this list is fish oil supplements which is loaded with Omega-3 fatty acids that is known to reduce inflammation in the heart.

Weight Management:

• Body weight is also essential to keep maintaining it at a good standard. Foot care is important as high heels can put pressure on the feet as obesity puts extra burden to the heart that needs to be controlled or maintained appropriately with the help of diet control and exercising.

3. Lifestyle Changes

Controlled Exercise:

• Light and monitored exercise activity assists in toning muscles or existing muscular strength and endurance. To avoid causing their injuries, the workouts should not be done to the extent of exhaustion or based on how much the dog is willing to train but rather on its fitness level.

Stress Reduction:

• Do not become stressed if you have this condition as this may make your symptoms worse. Prolonged stress and adverse conditions should be averted so as to create a serene atmosphere in the house.

Regular Veterinary Check-Ups:

• Daily check-ups by the vet are mandatory due to the fact that the species is vulnerable to various ailments. Monitoring the specific disease periodically helps in modifying the dosages of the drugs or the methods of handling the dog depending on the current state of its health.

4. Monitoring and Supportive Care

Home Monitoring:

• Monitor changes in your dog’s breathing, eating habits, overall balance, and movements. If there is a need to note any changes, it helps to do it in order to identify problems that may occur at a later date.

Fluid Monitoring:

• Take appropriate measurements on the amount of fluids the dog should be given and the amount of fluids that have been expelled from the body to avoid complications related to fluid overload.

Oxygen Therapy:

• It is also given at home or in veterinary clinics to manage the serious cases of excessive breathing rates in dogs.

5. Advanced Interventions

Thoracocentesis and Abdominocentesis:

• In instances where pleural effusion occurs or patients present with ascites, it is not uncommon for a vet to use procedures that have the effect of removing the excessive fluids and reducing the pressure on the organs.

Surgical Interventions:

• In rare incidences, a person may require corrective surgery because of Congenital Heart Disease or severe valvular disorder. This is often done at veterinary hospitals that are designed to handle complicated cases.

Implantable Devices:

• pacing devices can be used where severe abnormalities together with arrhythmias do not respond to drugs.

6. Palliative and End-of-Life Care

Pain Management:

• Maintaining the proper care of the skin, avoiding inactivity and administering the correct dose of pain relief drugs.

Quality of Life:

• It is crucial to keep the dog’s quality of life the top priority in those cases. This include placing an object that the dog seems to love sleeping on, the pet being softly spoken to, and other things which the dog loves to do are done.

Humane Euthanasia:

• If heart failure reaches a stage whereby the dog decorum is severely affected and the symptoms cannot be controlled, decisions on quality and widely acceptable euthanasia be made with the veterinarian.

As with most diseases, management of heart failure in dogs is a multifaceted process that might include medications, special feedings, modifications in lifestyle and routine veterinary care. The aims are to alleviate suffering, enhance general wellbeing and extend the possible years of functioning of the affected four-legged friend. However, it is critical that ongoing communication with a veterinarian is maintained to fine-tune treatments in response to changes in the course of the condition and to provide optimal care to affected dogs.

Prognosis

Heart failure in dogs ranges from chronic congestive heart failure where the condition gradually worsens with no possibility of complete recovery to acute heart failure where a sudden deterioration makes it possible to arrest the ailment completely. Heart failure in dogs is a chronic and uncurable disease, but it is possible to extend the period of the animal’s comfortable and happy life for several months, sometimes years, with proper treatment.

End-of-Life Care

In advanced stages of heart failure managing the process may turn to euthanasia and provide only the opportunity to let the dog’s end with comfort. That is pain control and treatment for symptoms and it also concerns making an ethical decision when continual suffering make’s the dog’s life not worth living.

As with many diseases seen in dogs, heart failure is a chronic condition, which implies constant medical attention and management for the affected animals and the desire to achieve the highest possible quality of life with this disease.
