My dog has diarrhea, vomiting, and weak back legs. What's wrong?

Updated On September 23rd, 2025

Pet's info: Dog | Border Collie | Male | unneutered | 1 year and 1 month old | 30 lbs

My 1 year and 3 month old Border Collie has had Diarrhea for the last 3 days, the first day with a little bit of vomiting. As of tonight it is difficult for him to move his back legs, as if he is stuck in a pooping position, but he is no longer pooping. We plan to take him to the vet in the morning, but if you have any information on possible causes on what is wrong with his legs that would be very helpful. He isn't just a dog to me. Thank you.

It sounds as Lycan is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.
