straight legs - Page 1

I understand that as an adult dog it is desirable for the toes to turn slightly out or be completely straight.  With a puppy that has completely straight legs (frontal view) down to their toes, is it normal for their toes to occasionally turn ever so slightly inwards and for their legs to wobble a little when they are sitting in this position?  The pup I am referring to has completely straight legs 95% of the time, but sometimes will sit a little strange and the legs will shake.  Is there an age that this would concern you?  I am so used to "outies" I don't know what to make of this.

Anyone?  My two concerns are is this due to poor ligaments or may the pup be slightly bow-legged but doesn't look it yet or is this completely normal for a puppy with straight legs and toes?  Will the pup grow out of it?  I know I can't be the first to see a pup like this.

I probably got a lot of people to look at their puppies' legs, lol!  I guess it must not be something to worry about because if it were I'm sure someone would know something ;)
