My dog is panting, not eating, lethargic, and restless. What's wrong?

Updated On September 23rd, 2025

Pet's info: Dog | Rottweiler | Female | spayed | 7 years and 2 months old | 115 lbs

My dog hasn't eaten in 24 hours. She has been panting and breathing heavily a lot this week even though it hasn't been hot. She is very lethargic and tired, yet restless. What could be wrong?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I am sorry Layla is not herself! There are many possibilities for the symptoms you are describing: Not eating, panting, lethargic, restless. Some things that could be wrong: she could have a fever, she could be in pain (in her belly), she could be in heart failure, have pneumonia or other lung or heart issue, she could have eaten something that is now stuck in her intestines or stomach, lyme disease, she could be bleeding some where or she could have a metabolic problem like kidney failure, liver disease, etc. The possibilities are long and some are serious. The most serious symptom you are reporting is the trouble breathing, that alone is a reason to take her to your Vet today. I wish you the best of luck!
