Fatigue in Dogs: Razzle Goes Listless. What Would You Do If It Was Your Dog?
Lethargy, weakness, or fatigue in dogs are vague symptoms. However, they can mean that your dog is seriously ill.
Dogs are normally bundles of energy and joy. Naturally, a day of fun can make your dog tired. But what if they become more listless and fatigued than is reasonable for the amount of activity?

Potential causes of weakness and lethargy in dogs include:
- infections
- fever
- heart issues
- liver issues
- diabetes
- low blood sugar levels
- anemia
- severe dehydration
- severe pain
- poisoning
However ambiguous symptom unexplained fatigue might be, it means your dog’s health is in trouble. Even with the absence of other obvious signs, I’d see a veterinarian as soon as possible.
Cookie looked more tired than it made sense when she had a bout of pancreatitis. Jasmine was listless when she suffered from pain in her neck.
Razzle’s story
Razzle was a 5-year-old Cavalier King Charles Spaniel.
You can see how lovable and loved Razzle was. Such a wonderful boy. Every day he was busy playing and giving love.
First symptoms
One Friday afternoon, Razzle became a bit listless. Maybe he had a little bit too much fun? Or perhaps he felt a little under the weather?
His parents weren’t sure how concerned they should be.
Razzle keeps getting worse
But as the weekend went on, Razzle kept getting quieter and weaker. By Monday morning, he was barely able to stand and looked jaundiced.
That’s when his parents realized something was seriously wrong. Concerned that they waited too long, they rushed Razzle to a veterinarian.
Razzle’s condition was life-threatening
Immediately, Razzle required intensive, aggressive treatment. If he received medical help any later, he could have died.
Can you figure out what was wrong with Razzle? Do you know what conditions can cause severe lethargy and jaundice? What would you do if Razzle was your dog?
