Easty, westy feet on a puppy can correct itself. Puppies go through some crazy growth stages and yes it can happen. If you have a show dog, being slightly toed out can still be ok, if you can stack your dog out of it. So it really just depends the age of the dog and the severity of it. When you stack the front of your dog, grab the front leg at the elbow and stack that front leg straight. If when you release the elbow from your hand the foot then turns out, your dog is out at the elbows. Being out at the elbows will cause the foot to turn out. I hope I explained that well. lol
Somethings to consider, are you hoping for a show potential?
Can you stack your dog out of it ...if its a show potential?
If you are not interested in showing your dog and its nothing more then a cosmetic issue then dont be too concerned. It wont cause serious health issues. Thats actually something that happens frequently with show dogs that have a straight front. Just because your dog toes out slightly doesnt mean it cannot be shown (depending on the severity of it) We had a beautiful female Amstaff that one foot toed in slightly. She was championed easily and took breed a few times as well AKC. We knew how to hide it well in the ring and for breeding she had to be bred to a male with a PERFECT front. I also championed my APBT bitch UKC easily and she was slightly toed out. Depending on the other qualities of the dog, you still have a chance.
