Why is my dog lethargic and only wants to rest after eating?

Updated on September 23rd, 2025

Pet's info: Dog | Shih Tzu | Male | unneutered | 2 years and 1 month old | 7.716 lbs

My dog is lethargic and is lacking of energy. Whenever he eats, he’s gaining some little energy but mostly wants to just rest. What could be the problem?

Yeontan is experiencing very general symptoms of disease, these symptoms could fit almost any internal condition, maybe he is suffering from nausea due to a gastrointestinal disease and maybe he is in pain, from the symptoms described it's very hard to know. i would recommend taking him to the vet as soon as possible in order to get him checked, if he doesn't show any other obvious symptoms during the examination, a blood test and possibly an ultrasound will be needed in order to try and find out what is wrong with him.

Why is my dog lethargic, not moving, but still eating and drinking?

I am sorry tokie is not feeling well. Unfortunately a large range of problems can cause a dog to be tired and lethargic. I would recommend a vet exam for a good physical exam to help pin point why tokie is not feeling well. With an older dog it is possible arthritis, infection, or even endocrine disease like hypothyroid is causing these changes. Your vet might want to run some blood work or take x-rays to get to the bottom of the problem. Hope Tokie feels better soon

Why is my dog suddenly lethargic and sleeping more than usual?

Thanks for using Petco Pet Education Center, formerly Petcoach! Lack of energy can be the sign of many things that go from just being tired to actually representing a problem like due to pain for example. If he is otherwise fine, I recommend you keep a close eye on him for now. If there is no improvement within the next 2-3 days, have him evaluated by a veterinarian for further assessment and treatment. Good luck and have a great day!

My dog is lethargic after a trip. Is he sick, tired, or ate something?

He could simply be tired, but if it goes on for more than 24 hours, I'd recommend a check up with his vet to make sure nothing is going on. He could have pulled a muscle or eaten something more than you realized during the visit. If he's not eating, extremely lethargic, or vomiting, I'd go to the vet ASAP.

My dog is suddenly lazy, not eating, and sleeping a lot. Is he sick?

Poor Pocholo! It definitely sounds like he isn't feeling well for some reason. Unfortunately, these symptoms are very vague and could be caused by almost any type of illness or injury, so there's no way to say what might be wrong without being able to examine him. I would recommend taking him to the vet for a check-up as soon as you are able to - he/she can do some blood work or other testing if needed to help determine what's wrong and get him started on appropriate treatment for the problem.
