multiple, but Ill start with one

Question
I'm wondering about nutrition to help with some healing.  Taiko is a 6 year old Silky Terrier, his is well bred and is actually larger than he should be (even though he is pure bred - 12 lbs).  

When he was a year old he was hit by a car, broke the upper part of his leg right at the ball.  The Vet went in and took out the slivers and said he would be fine without any further pins or anything.  They had to do a second surgery right away though due to the fact that the bone continued to grow - they just cut off the ends to stop the growing plate (or something like that).  

Fast forward, no apparent problems, he jumps, runs, lunges, etc (another problem for another time). Recently he started not bearing any weight on this left hind leg when he would get up from a resting position. I have also noticed that there are times when he doesn't bear weight (when standing at the window, etc) and as I examined to see if he had a 'bite' or something, I noticed that it seems that his leg is a bit smaller in bulk than the other leg.

I took him to the vet and she thought it was his knee, but an x-ray shows that the leg top is resting right up at the socket area - it should be more 'free floating'.  

She suggests he go to a specialist vet and that he may need to have surgery again.  Very expensive and they are not in our area so we have to travel quite a distance - we live in a small town.

I am wondering if there is a way to use nutrition and some alternative medicine things to get the body to heal.  I used some homeopathic remedies to get him through the weekend when we couldn't get him in due to being overbooked, they seemed to help him.  

We believe in the alternative healing but I can't find any info on how to get more info from a wholistic veterinarian.  

The vet did give us some suggestions of 1. Cosequin Glucosamine Candratin, 2. Omega 3 Fatty Acids, 3. Vitamin C (500 mg every 12 hrs) and 4.  Antioxidants.  The homeopathic I used was Arnica Montana, and I've been thinking perhaps some Rhus Tox (if you have any knowledge of these things).

Can you refer me to someone that might be able to help me know if 'rest' and supplements can help his body to develop some cartilage or whatever?

Any suggestions?  

Answer
At this point, it's hard to say whether homeopathic 'treatments' will do anything, because of what had to be done to the bone when it was broken. However, the suggestions by your vet are, for the most part, good ones. Glucosamine Chondroitin with MSM is what I would recommend, and fish oil for omega 3's. Fish oil (NOT liver oil) is the best source of omega 3's for both dogs and people. You also need to give vitamin E if you choose to add any kind of oils to his food. I do not recommend giving vitamin C, because dogs manufacture their own vitamin C. What kind of antioxidants were recommended? I would recommend apple cider vinegar. I use it, and it's good for a LOT of things, just like in people. You can put a teaspoon in your dog's food, and he probably won't even know it's there. Or, you can put it in an oral syringe and squirt it in his mouth.

I'm not sure that using Arnica Montana is going to be all that helpful either, because it is used primarily to treat muscle sprains and bruises. I'm not familiar with Rhus Tox, but I did some quick research on it, and it sounds like it might help, since it is often given to dogs with arthritis.
