I feel I am very bonded to both my GSDs. They are right next to me wherever I am at home. I never felt that with my mix Clover, she has never been that into me!
But when I went to SchH training the other night and watched the dogs happily focus on their owners, mine don't do that w/me.
I adopted Kacie when Onyx was 5 mos. and I don't regret it but they are strongly bonded to each other, you should see them play. I do take Onyx to training and walk them seperate and together, but that "watch me" doesn't really ever happen with us. I love to watch the dogs in training giving that joyful eye contact w/their handlers...
