Hi,
Re the splayed legs. Is hew chest rather flat? this could be swimmers, and can be sorted out. Type swimmers into the search box, after clicking search at the top ot the page.
I would start with masaging the legs and body into the right shape.
I had a pup who must have had a front paw bent back at the front pastern in the wrong direction, in the womb, it looked back to front!
the ligaments seemed pulled. I massaged the paw daily, and by the time they got on their feet there was no sign of the problem. I suppose it is because the bones are so soft and only grissle, that things can be persuaded back into prper shape/alignment.
Those puppy weights are very good, asin my breed pups average 10 - 12 onces, and |I have had 6 ounces to 18 ounces, that have all turned out normal size.
