1. Restrict his activity. Keep your dog from running, jumping, or playing too much so that his shoulder can heal properly.
2. Keep your dog's shoulder warm. Apply a warm, moist compress to his shoulder for 10-15 minutes several times a day. This can help to reduce inflammation and pain.
3. Massage your dog's shoulder. Gently massage your dog's shoulder and the surrounding muscles for 5-10 minutes a few times a day. This can help to improve circulation and flexibility.
4. Give your dog pain medication. If your dog is in pain, you can give him over-the-counter pain medication such as aspirin or ibuprofen. However, be sure to talk to your veterinarian before giving your dog any medication.
5. Take your dog to the veterinarian. If your dog's limping does not improve within a few days, or if he seems to be in pain, it's important to take him to the veterinarian.
