My dog isn't pb, but apparently received enough genes from mama to behave in many of the same ways!
--This velcro thing! I thought he'd grow out of it, that it was a young pup thing. At just shy of 9 months, nope. Still waits outside the bathroom door when I shower, still wants to accompany me to the potty. Still wants to be wherever I am. Curious about every single thing I'm doing.
--The intelligence and intensity! For a mutt, this guy is pretty smart! When we're "training," he is really focused on what we're doing. I'm honestly extremely surprised by this. VERY pleasantly so. I mean, he LIKES it. He LIKES to focus and earn his treat or praise. My other two, (non-GSD) just didn't hold focus like this guy can.
--The sensitive tummy stuff is the bad "surprise." His mom was fed cheap crap (not my choice, not my dog) and she never had any issues, not a single one. (Other than a whole lot more poop) Sigh.
--The bond. I knew, but didn't know, how strong a GSD/ (mix) can bond to the owner. Sure, I saw it with my son and his WGSD... and I bonded to that dog, too, but... I didn't really understand it until Bailey. I have two other dogs and I love them with all my heart. I'm bonded to them, of course, but it isn't the same. My oldest dog is my sweetheart, but she never followed me around like this, never wanted my attention like this, never was so "driven" like this guy is. Hate to say it, but she isn't anywhere near as smart as he is. I feel like a traitor, but it's true. My middle dog is more bonded to my bf, for some stupid reason. (I exercise, feed, do almost everything - yet truth be told, she is "his" dog.)
