Ours are rescues, so no relation. The blonde (Athena) was adopted when she was about 3yrs old from a rescue out of FL, she's 13yrs old now & the black one (Gingy), we took in a year ago when the owners could no longer take care of her, she's 4yrs. old, They aren't really bonded yet, like I'm sure yours must be. I'm hoping in time they will be, but Gingy likes to fuss (not bark, fuss, it's funny & weird, rofl) a lot. We had a mini male schnauzer, Athena & him were bonded & cuddled in the winter, so cute, he kept her warm. But he passed away this year at the age of 16. It was a heartbreaking time & Athena was depressed for a while too. They had been together for 10yrs. But she's better now. We love dogs & ours are so spoiled. I know this thread is for MBs, but I'd love to see a pic of yours, if you want to post one. I'm sure no one would mind, hopefully.
