Why is my dog weak, skinny, and can't walk on her back legs?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female

My dog has an appetite and she doesn’t seem sick no leaking a fluid but she can’t seem to walk on her back legs I don’t know if she can be constipated because she can walk but she’s really weak and it looks like she’s skinnier from the back part of her body could it be from constipation could it be something minor what are the chances

If Foxxie is really weak, looks skinner on her back part of the body, and can't seem to walk, I would say this is pretty serious. I would not think this would be caused by something minor and I don't suspect constipation. There could be a problem with her spine, if she isn't spayed she could have a closed pyometra, or another disease causing her symptoms. Without seeing her in person, I can't make a diagnosis but she needs to see a vet immediately. Please take her into one now.
