The girls are 17 weeks old (not 21 weeks ‍♀). I remember the first thing I asked the vet about the xray was “are they uniform?“
I was concerned if one was going to be big or one was tiny… All 5 were uniform. Maximus is a beast, he was the sixth and late four hours later. He was not on the xray.‍♀
So happy that 17 weeks later they’re still uniform. all just under a foot tall at the top of the Withers.
