Why is my dog suddenly lethargic with shaky legs and sensitive to touch?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female | spayed | 5 years and 7 months old | 20 lbs

My 5 year old Maltipoo all of the sudden is lethargic and doesn't want to get out of bed. She is eating and drinking and wagging her tail but doesn't want to be touched. We stood her up and her back legs are shaky...she can stand and doesn't cry. I'm qnotbsure what brought this on?

Any abrupt change in demeanor or behavior should be checked by a vet as soon as possible. Sometimes this is the only way our pets can tell us something is wrong. Hiding and not wanting to be touched can indicate pain or discomfort. She could have a hidden injury you weren't aware of, she could have an infection of some kind, eaten something that didn't agree with her, there are a number of possibilities. Your vet will do an exam, labwork and probably x-rays and based on these results will be better able to tell you what is wrong and how best to treat it.
