Weakness in Dogs: What Causes It?

A variety of issues may be causing your dog to feel and act physically weak. These range from temporary and acute problems to more serious and chronic issues that can be fatal. Infection and disease are the two most common issues affecting dog strength and development.

Infection in dogs

Infection can contribute significantly to overall canine weakness and fatigue. In most cases, these infections cause weakness in addition to other symptoms. Heartworm disease, kennel cough, and canine distemper are three of the most common infections that affect dogs. Heartworm disease, also known as dirofilariasis, is caused by a blood-borne parasite that enters your dog’s heart via mosquito bites. Lethargy and muscle weakness, as well as fever, can be symptoms. Heartworm disease is treated with a series of medications prescribed by a veterinarian.

Fever, lethargy, discharge from the eyes and nose, and coughing are some of the symptoms of distemper. It is possible that it will cause neurological issues. Distemper symptoms are diverse and differ from dog to dog.

Kennel cough is another common and highly contagious infection. Kennel cough is an upper respiratory infection that is commonly contracted in areas with a high density of infected animals. Kennel cough symptoms include muscle weakness, fatigue, and fever, and treatment includes cough suppressants and antibiotics. These disease can be extremely fatal for a weak puppy

Heartworm disease is caused by heartworms, which are spread via mosquito bites. Lethargy, depression, fever, and weakness can all be symptoms of heartworm infection. The best option for prevention is to use oral or injectable medications.

Respiratory illness might also be one of the reasons leading to weakness in dogs. One of the worst dog pugs is an example of such a weak dog, they face several types of respiratory illness, since their muzzle is short and nostril is pressed. Also their small compact body makes these cute furry babies come in contact with several kinds of breathing issues as well. 

Diseases in dogs

Myasthenia Gravis

There are numerous diseases that can impair a dog’s strength and energy levels. Myasthenia Gravis and Congenital Myasthenia Gravis are the two most common diseases that cause weakness in dogs. Myasthenia Gravis is an autoimmune disease that causes skeletal muscle weakness or fatigue in dogs. This can be intermittent, coming and going in waves, or it can be chronic and long-lasting. When physical weakness occurs intermittently, it is frequently exacerbated by activity (such as walking, running, and playing) and relieved by rest.

In Myasthenia Gravis, there is a miscommunication between your dog’s nerves and skeletal muscles, which results in muscle pain and suffering. Your dog’s muscles contract incorrectly as a result of the discord between the delivery of impulses between nerves and muscles, resulting in weakness. Myasthenia Gravis is a disease that develops between the ages of 1 and 4. Myasthenia Gravis is classified into three types: mild, which affects only one body part, moderate, which affects multiple limbs, and severe, which is usually fatal. Congenital Myasthenia Gravis, on the other hand, appears at birth in puppies with a lack of acetylcholine receptors on their muscles.

Symptoms of Dog Weakness

One of the most common symptoms is fatigue after only a short period of exercise. Other signs to look for include a strange gait, body tremors, shaking, excessive drooling, and heavy breathing. When observing your dog, try to notice if there are any other symptoms present in addition to the fatigue. Is there a release? Is your dog running a fever? Is there nausea or abdominal pain? Examining your dog’s medical history can also help you figure out what’s causing the problem. Muscle weakness in dogs is extremely debilitating and difficult to diagnose. Infection, disease, illness, and general malaise are all possible causes. Most of the time, a quick veterinarian exam will reveal the root cause of your dog’s weakness.

Coughing, wheezing, breathing difficulties, and nasal discharge are all symptoms of a respiratory issue. Symptoms can range from a simple cold to canine influenza, kennel cough, or heart failure. Hearing a honking noise could mean your dog has tracheal collapse, which is common in small dog breeds.

It is often beneficial to keep notes and a chart of when your dog’s symptoms began, the severity of the symptoms, and any medications he or she is taking. If you have any concerns, a good rule of thumb is to always consult a veterinarian if your dog has any concerns or symptoms. Remember that many diseases and infections can be treated if they are detected early.

Visiting a Vet for Your Sick Dog

Unfortunately, your pet will not approach you and inform you that they are ill, hence the management of week dog is all up to you and must be taken care of very cautiously. As a result, it’s critical for dog owners to recognise the early signs as soon as possible. If your dog exhibits any of these symptoms, make an appointment with your veterinarian. Your veterinarian will inquire about your dog’s medical history and may conduct tests.
