it would be helpful if you could get an x-ray - maybe a local doctor would be nice enough to do that for your dog's leg.
It's possible that the break has not healed because the bones were too far apart.
It's more likely that it's healing a little crooked. That may cause the inflammation and swelling. You can try making a little cut to see if any fluid comes out. Usually it's the pressure of the fluid from the swelling that causes pain in the nerves.
You have to make sure you have everything as clean as possible for this. Take a sharp knife and boil it in a pot of water for 5 minutes. shave a small area on the leg where the swelling is the worst - find a spot that your dog can lick because that will help it heal.
Put some alcohol and iodine if you have it on there with a clean cloth. Empty the pot and wait for the knife to cool down a little, then take it out of the pot and make sure you only touch the handle.
Poke the knife in carefully maybe half a centimeter, and see if any clear liquid or clear liquid mixed with a little blood comes out. If it is ONLY blood, stop. If you get clear or pink liquid, squeeze the leg gently and get as much out as you can. Let your dog lick it clean afterwards. Do not put alcohol on the open wound.
Give it 24 hours and see what happens. It may fill up again, so you can repeat the procedure every day. Try to get some anti-inflammatory medication such as Meloxicam (ask a pharmacist, medications are usually sold under different names in different countries). Ketoprofen, Ibuprofen and Naproxen are good too.
Give your dog 1/4 the human dose and make sure he eats first or drinks milk because these medications upset the stomach.View Thread
Iif your dog is eating and drinking ok that's a good sign. When he had the accident, did he bleed ? If yes, then check the wounds. Wash off any blood with warm water and see if there is any thick yellow fluid which would be pus. If there's a lot, he'll need an antibiotic. You can try a human antibiotic and reduce the dose according to weight, like maybe 1/4 human strength. Check with a pharmacy if any such medication is available in your country without a prescription.
If there is only a little pus at the edge of the wound, keep it clean by washing it once a day with warm, salty water.
If there is no pus, check to see if touching the wound is more painful than where there is no wound. If it's hot and very painful right at the wound, there might be an infection inside. Remember "hotl body temperature is normal for a dog.View Thread
my puppy has a broken forearm. It's a clean break with good approximation. I asked a Vet to treat it with a splint. She expressed concern about the probability of infection, and recommended getting pins put in by an ortho specialist. I think an open wound penetrating the bone marrow is far more susceptible to infection than a bandaged-up closed fracture. I've seen severe complications in humans leading to permanent neuritis. The Vet still says any dirt getting under the bandage of the splint is just as dangerous as on a pin insertion site. I think she's wrong and just trying to upsell a costly specialty procedure.View Thread
