Austrailian Shepherd folded ears, and bowed legs

Question
Our aussie is 8 months old. He has folded ears, nearly prick.  The breeder glued his ears down on his face, which we continued to try to do until he was about 4.5 months old.  She recommended doing until his was done teething.  When was teething end? Would it be worth doing again.  We do like the look of the soft laydown ears, which seems to be more of the breed standard.  Further,  I have recently become concerned about his front legs, they are looking a bit bowed.  Or, the legs are straight, but when he walks, he appears to place his feet closer together, than his shoulders are wide.  Make sense?  Is there any activity, or floor surface, or toe nail issue which needs to be avoided regarding straight front legs and bow-leggedness.  He eats puppy chow, with cottage cheese, weighs 40 lbs. and is an active happy dog. thanks

Answer
Well, puppy chow is not the best food, in my opinion, but regardless of that, some dogs are not entirely straight-legged.  In the past, Aussies were bred more for herding and guarding abilities than for conformation, although a dog that could work hard like that over the course of a lifetime was generally a dog that was sound.  
Teething is over at about five months, so nothing you do now will be likely to correct the ear fault.  If this is not a show dog, then ears don't really matter.  (Even if he is from show lines, please don't breed him and perpetuate the fault.)  
I would get this dog on an "all life stages" food that is better quality, and avoid the cottage cheese, which could be giving him an excess of calcium.  I feed Innova, but there are many other top quality foods.  I find that nothing in the supermarket meets my standards;-)
When you consider a food in kilocalories per cup, you don't feed as much of the better foods, so the cost is not that much higher.  If you have to supplement for bulk, many owners advise using cut up green beans, although I don't do that.
