My Puppy Hurt His Back Rt Leg And He Wont Put Any Weight On It . Can I Fix It At Home?

I have a massive pittbull that went through something similar.  He was chasing a dog in heat and hurt his hind leg and wouldnt put any pressure on it.  I wrapped his leg with an ACE bandage (from paw up...) and then taped it.  After four days he is doing much better BUT he is still not putting pressure on the leg.  What needs to be done now in order for him to regain trust and strength in the hurt leg is to force him to use it by taping the uninjured leg.

I also am a proud owner of a pit bull pup going on 4 months. My neighbor stepped on his leg and it seemed to be a knee injury, my brother in law suggested pain killer ointment, imported but available at walmart or kmart, called MAMISAN, a splint,
 but we used a bandage wide enough so the leg would not bend, its been four long days but he is showing signs of improvement! I hope this helps anyone with a similar problem!!

Maybe we could help I love dogs and puppy's so so so so much
