My dog's leg is swollen from knee to paw. Is it serious? What to do?

The leash must be removed immediately to relieve the obstruction of the blood flow. If the leg is evidently distorted or broken or her foot is cold to touch she needs urgent vet care otherwise monitor for a reduction in swelling and discomfort over 12 hours or so

I can see the swelling from the pictures you posted. It appears the swelling goes form the foot all the way to the knee. I see that you live in an area where snake bite is possible. I would check thoroughly for any punctures along the entire leg and see if Diamond is painful in any particular area. If not, other causes of swelling like this could include infection, allergic reaction, trauma, cancer, among others. Sometimes swelling in an entire limb can be caused by decreased lymphatic flow - this can be caused by damage to lymph nodes or a structure under the skin or inside the body that is impinging on the lymph flow. I have also seen swelling like this with a flare-up of a mast cell tumor elsewhere on the body. I agree with your vet; if the medications prescribed to not make a difference, additional diagnostics are warranted. They may include bloodwork, abdominal x-rays, tick testing, or sampling of any small masses found.

I really feel that Lexi needs to have a full veterinary exam to determine what has happened. From the pictures, one possibility is that she is adjusting how she sits to extend the injured leg out - if she is not putting any weight on that leg then she may have broken it, or injured a ligament. There are also a couple of illnesses that can occur in a young growing dog, thses can be diagnosed with an exam and xrays. If she is limping she should have pain relief - Do not use any human medicines as these may be toxic to her.

It still could be broken even if you can touch it, there may be a fracture in the bone. The only way to rule out a broken bone is with an x-ray. It's quite serious Layla's leg has been swollen for 8 days and she can't stand on it. That means she has been in pain for 8 days. I would take her into a vet immediately.

This looks like a severe bite wound and it would need to be examined by a veterinarian. This wound needs to be cleaned and disinfected and your dog will need pain medicine and antibiotics, Please take Tyson to a veterinarian for wound care. The swelling may be a sign of a fracture or infection.

Ouch, poor Zoey! She sounds quite painful if she won't put weight on the leg. She could have broken a bone, or torn a ligament in her knee. I would rest her tonight, and have her seen by a vet first thing in the morning. The vet can diagnose what is causing her swelling and pain, and can treat her for it. Please do not give her any human pain medications, as many are toxic to dogs and can be fatal if given. The vet can prescribe safe medications for her.

Please have Ann examined by your veterinarian or at the nearest veterinary ER today. That wound will likely need to be explored and debrided surgically. This will require anesthesia. A culture/sensitivity and biopsy of the area should be submitted as well. The C&S will identify any bacteria as well as the best antibiotic to use in treatment. Even though she was on antibiotics, if the bacteria was not susceptible to them, they would be ineffective. A biopsy will rule out neoplasia (cancer). Either can cause delayed healing or non-healing. If infection gets into the bone, it could turn into a life threatening condition. Place an e-collar (cone) on her to prevent licking until she sees a doctor.
