What You Should Do to Help

If you notice that your dog is acting lethargic or isn't tolerating their usual levels of exercise, it's important not to force them to run. Follow their cues, and allow them to stop playing or cut their walk short if necessary. Keep a close eye on them, watching for other serious symptoms. If you notice any other worrisome behaviours, you should contact your veterinarian right away. If your dog doesn't show any other symptoms, wait a day or two. If your pup's energy doesn't improve or their condition worsens, contact your vet. That being said, if they show extreme symptoms, such as fainting or collapse, get them to an emergency clinic immediately.

Diagnosing Your Dog

Once at the vet, your dog will be thoroughly examined. The vet will likely look for any signs of lameness, injury, or pain, as well as any possible tumours. He or she will also perform blood and urine tests to check for underlying health conditions. It's likely that your pup will also be hooked up to an electrocardiograph machine to check the electrical activity of their heart, and will be given chest x-rays to examine their heart and lungs. Your vet might also recommend an ultrasound, CT scan, or MRI to help diagnose your pup's condition. You can help achieve a proper diagnosis by providing your vet with a list of any medications your dog takes, talking over the details about their diet and lifestyle, and mentioning any other symptoms or changes you've noticed in your pup.

What to Do After Diagnosis

Lethargy and exercise intolerance are symptoms of a problem, not a condition by themselves. The type of care your dog needs will depend on the condition with which they are diagnosed. Depending on the vet's assessment, your pooch might recover and return to their former levels of activity. However, heart disease in dogs, as well as other progressive illnesses, may require changes in exercise and activity for the rest of their life. Talk to your vet about your pup's condition and how much physical activity they can safely handle.

Alternatives to Exercise

If your dog is restricted from vigorous activity and exercise, it can be a challenge to control their weight. Because excess weight can exacerbate some ailments, this is a challenge that must be addressed. Depending on your pup's diagnosis and treatment plan, your vet might place them on a special therapeutic meal plan that's appropriate to their condition. Otherwise, talk to your vet about placing them on weight control dog food that can help them keep off the "puppy fat" in the absence of exercise. Making sure your dog is eating an age-appropriate dog food can also help manage their weight. Proper nutrition is also vital. If your dog is not receiving the right nutrients they need to keep their energy levels up, this could be a contributing factor to their lethargy. Be sure to talk to your vet about overall food recommendations even if they do not need a specific condition-based dog food.

Age Considerations

Of course, it's normal for dogs to slow down a bit as they get older. Joint problems, weight gain, and simply growing more tired with age are all factors that could cause an older dog to be less active. But older dogs are also more susceptible to the types of illnesses that cause lethargy and exercise intolerance; regardless of your dog's age, if they are noticeably more tired than usual, it's important not to chalk it up to just being a senior. These are potential red flags that should never be ignored.

A dog's activity level can be a strong indicator of their health. That's why as a pet parent, it's important to pay close attention to what's normal for your pooch so that you'll be able to recognise when they are not acting quite like themselves. If you're not in the habit of routinely playing with or walking your dog, start now so that you'll be familiar with their normal level of activity. By acting quickly when your dog is acting lethargic, you could help catch a serious illness in its early stages and improve your pet's chances of continuing to live a healthy, happy life.
