I'm sorry to hear about your puppy's troubles. It must be worrying to see your German Shepherd unable to use his back legs. There are several possible reasons for this, including a condition known as hip dysplasia, spinal issues, or even trauma from an injury. Puppies can also suffer from a condition called degenerative myelopathy, although it's more common in older dogs.
First, check if your puppy is in any obvious pain or if there's swelling or tenderness when you touch the back or legs. Ensuring your fur baby is comfortable is crucial. Create a soft, confined space where he can lie down without having to move around too much, ensuring his needs are within reach. Keep him calm and encourage rest for now.
Please watch for any signs of pain, such as yelping, loss of appetite, or changes in behavior. If you notice any of these or if his condition worsens, it could be more serious and might require urgent attention.
Considering the potential severity, I recommend booking a video consult with us on Dial A Vet. A thorough examination by a professional will help determine the exact cause and the best course of action to get your puppy back to his playful self.
