It's crucial to seek veterinary care immediately. Possible causes for your dog's symptoms include:
* Injury: A fall, hit by a car, or even a sudden, forceful movement can cause muscle or ligament damage.
* Infections: Bone infections (osteomyelitis) or infections in the joints (septic arthritis) can cause pain and lameness.
* Neurological Problems: Intervertebral disc disease (a slipped disc), spinal cord injuries, or neurological disorders can affect limb function.
* Bone Disease: Conditions like bone cancer or osteosarcoma can cause pain and weakness in the legs.
* Congenital Issues: Rarely, a birth defect or genetic predisposition could be the culprit.
Don't delay getting your dog to a veterinarian. They will be able to properly diagnose the issue and provide the best course of treatment for your Rottweiler.
