My dehydrated dog is lethargic. Why isn't Pedialyte working?

Updated On September 23rd, 2025

Pet's info: Dog | Miniature Poodle | Female | spayed | 8 years and 5 months old

My dog seems dehydrated. Her CRT is more than 2 seconds. She has low energy and doesn’t want to walk much. I’ve given her pedialyte. What might this be?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. There are many causes of dehydration and given her symptoms, I would recommend having her blood tested to rule out kidney disease or any other systemic diseases / infections. She will likely need a course of subcutaneous fluids, which is when fluid is administered under the skin and absorbed by the body. This is an effective way to hydrate an animal and is well tolerated. I hope this helps guide you in the right direction. Please do not hesitate to contact me with any further questions or concerns that you may have.
