Generally, if your dog's limp isn't severe, you can just monitor your pup's progress at home over 24-48 hours, watching for more symptoms or to see if the limp becomes more pronounced. If the limp doesn't start resolving itself, is getting worse, or is accompanied by whining or yelping, it's time to call your vet or visit your nearest emergency pet hospital. Your veterinarian has the training and knowledge needed to diagnose the cause and determine the severity of your pup's pain. Your dog's breed, history, age, and general health will all be considered in the diagnosis, as well as the prescribed treatment plan. While it's not always necessary to visit the vet as soon as your dog starts limping, there are some situations where your pooch requires veterinary care. If your pup is suffering from a chronic condition that is causing them to limp, or an injury such as a muscle or tendon tear, cold laser therapy may be an effective way to help relieve inflammation and speed healing. Limping for more than 24 hours without improvement is one situation where you should contact your veterinarian or your nearest emergency animal clinic for care.
