We lost our first pup of 15 years old about 4 years ago. I still tear up thinking of my boy. It's better to love and lost than not have loved at all. Your pup was lucky you found her, as you are to have found her.
The 10.5 is a little too long for me, the toe ended up creasing weird. I used two insoles to alleviate the toe creasing, so now they fit like my size 10s, lol. The size 10s are good widthwise, but a smidgen too short, length wise. I guess I'm a size 10.25 in the 991v2.
I've worn my reds twice and they're yellowing like that, my blues I've worn a ton more and they're still white. I've tried everything I can think of to get them white, to no avail.
