Many people have been there.

Your dog appears to be under the weather and not himself.

But when does it actually border on lethargy and what might your dog be suffering from?

If your dog is lethargic but continues to eat and drink, this is a very non-specific symptom and could indicate a number of problems, all of which need to be addressed.

For some cases of lethargic dogs there are certainly home remedies while others require a visit to the vet, let’s shed some light on this topic.

My dog ​​is lethargic but he eats and drinks

If your dog is lethargic but eats and drinks, common causes include excessive exercise, boredom, fear, poisoning, inflammation, or medications, as well as mental or chronic disorders.

Having your dog lethargic but eating and drinking nonetheless is a good sign as it will avoid an emergency vet visit for nutrient deficiency.

However, some cases still need to be treated fairly quickly, while others depend only on easily modifiable external factors (such as exercise).

Additionally, circumstances and other symptoms can be crucial.

Here are some signs that indicate certain causes (however, this is not an exact science and a visit to the vet may still be necessary to rule out other problems).

  • Have you recently changed your training regimen? Excessive exercise or boredom come to mind.
  • Recent rescue or traumatic event? Fear is common.
  • Right after a walk or after devouring bad food? Check for poisoning
  • Visible wound? It could infect an infection or inflammation
  • Have you taken any medications recently? This could be the cause

Also, does your dog suffer from any of these symptoms too?


While the reverse is more common, it is possible that you have speeded up your dog’s exercise regimen too quickly.

If you’ve been on an extremely long hike or just introduced a new activity like biking or swimming, your dog may just be tired from it.

While this type of acute exercise is possible, it’s also possible that the exercise regimen has been too intense for your dog for weeks or months.

If nothing has changed and you are reasonably exercising your dog (which is essential), this is one of the unlikely causes of your dog’s lethargy.


If your dog is lethargic but continues to eat and drink, it could very well be that he is bored to death, possibly leading to depression or behavioral problems.

Some dog owners assume that only certain breeds need physical and mental exercise, but that is completely wrong.

What is true is that some breeds have higher exercise demands, but all need to be kept busy to avoid boredom that can resemble lethargy.

Boredom can also lead to hyperactivity inside the home or overexcitement outside, but both extremes are undesirable and should be investigated.

Fear or trauma

Loud noises, bad experiences, unfamiliar surfaces, and even a new environment can scare some dogs, especially if you’ve rescued a dog recently.

You will be the best judge of what may have led to that lethargy in your dog.

If your dog has started to seem lethargic but is still eating and drinking recently, you should try to remember the day he started to understand this.

It may just be a matter of time for your dog to stop drinking or eating altogether if lethargy is not addressed.

Food poisoning is more common than you might think considering there are many foods your dog shouldn’t dig into as they are toxic.

Your dog may also be feeling a little down because he has filled his face with that delicious dinner where the spices alone are enough to upset a dog’s stomach to the point that they look lethargic and sick but still drink, maybe even more for. compensate.

If your dog picked up something while walking outside and no longer looks like himself, keep poisoning in mind and see a vet as soon as possible.

Infection or inflammation

The inflammation can be caused by an infection which in turn could be the result of an injury.

Don’t you see any visible wounds? Then your vet might order a blood test.

This is often associated with fever and can definitely be the cause of your dog being lethargic.


Has your dog been given medication recently and is now lethargic but still eats and drinks? That switch could be the cause.

Check with your vet to see if this behavior change is a known side effect and if medications aren’t crucial at the moment, you can try banning them from your dog’s daily to-do list and see if it gets better and better again. active.

Old age, disorientation, depression

Aging dogs become calmer and calmer and if they are lethargic but continue to drink and eat normally, everything could be fine with your dog’s medical records.

Disorientation, restlessness or paranoia are serious symptoms and should be addressed.

If your senior dog is not only lethargic, but stares at random spots around the house, is disoriented and goes around a lot in circles, and so on you may be looking into canine dementia.

Diabetes, heart disease, immune system disorders, cancer

The more serious causes for your dog’s lethargy include diabetes, heart disease, immune system disorders, and cancer.

While you may already know about your dog’s diabetes or immune disorders, there may be health problems uncovered and only your vet can help you determine if your dog may be suffering from any of these conditions.

While there is no reason to be on the alert just because your dog appears to be unwell for one day, you should definitely examine him if your dog is behaving the same way for the next day for no apparent reason.

My dog ​​is lethargic and not himself

If your dog is lethargic and not himself, you should look into common causes such as exercise problems, fear, poisoning, nutritional deficiency, or neurological disorders.

Neurological reasons are fairly common causes your dog doesn’t feel like himself.

These causes primarily affect older dogs (hence why canine dementia plays an important role), but dogs of all breeds and ages can also be affected.

Behaviors that point towards neurological disorders include many circling behaviors or paranoid behaviors where your dog seems to see things inside the house as well.

My dog ​​looks sad and tired

Dogs that look sad and tired can suffer from depression, neurological disorders, or just plain boredom or old age.

Everyone has bad days and good days, but if your dog is acting lethargic or overly sad, you should ask your vet.

In mild cases, it’s just boredom or your dog may have mild separation anxiety if one of his favorite people or dogs just left.

While dogs tend to calm down with old age, it’s not common for everyone to suddenly become sad and tired.

In general, you are the best judge of your dog’s behavior and it is important to put things in perspective.

Sweet dogs have a completely different starting point than an active, excited dog who makes an eighty turn to become sad, tired, or even lethargic.

If your dog is already suffering from a diagnosed condition, this could be a particularly bad day for him.

When should i worry about my dog ​​being lethargic?

You should worry that your dog is lethargic if he does not react to stimuli and behaves strangely for 24 hours or more, while you should monitor the situation even more closely if he stops drinking and eating.

If you’re unsure, go the safe route and ask your vet.

Monitor your dog’s behavior closely, make sure he is drinking and eating and getting some exercise and try to involve him, but avoid disturbing him when he rests.
