If your dog seems lethargic and you’re unable to attribute it to a day of extensive physical activity, the best thing you can do is to contact your veterinarian. The list of possibilities when it comes to lethargy is lengthy.
Your dog will need a physical exam performed by their veterinarian to determine if there are any indications of pain, if they have a fever, if there are any signs of a tumor, and if their mucous membranes are pink.
Your dog may also need blood work to determine if they are anemic, if they’ve been exposed to any toxins, or if their blood sugar might be low.
