With Auggie, the very day I picked him up. There's a picture but my webhost is down so I can't link it. But he was mine from the moment we loaded into the car together to go home. He just... was.
With Pepper, I loved her since she was a puppy. Loving her was never the question. Loving her was always the problem LOL. It was the day I took her to the agility trial with me... actually, it's been almost a year, because it was the Sunday after my half-marathon last year and that's coming up at the end of the month here. I had her out to walk her around and let her potty. I was sitting on a wooden post fence and she had her paws up on my knees, and I was petting her face. And Auggie's breeder walked past us and said, "She looks really happy."
That was The Moment. In my head I thought "Well, ($*@." hahahaha. Because I still hadn't made up my mind if she was really staying or not, I was still going back and forth on if I was the best house for her or not. And when she said that, that just kind of sealed the deal.
With Payton, I was kind of in shock over being so impulsive for a few days LOL. I LOVED him, he was so cute, but it was bizarre to me hahaha. I jokingly say that I knew he was a member of my family on the Friday night after I got him when he bit my arm and left a bruise XD I don't think there was really a "moment" with him like with Auggie or Pepper. If anything it happened in reverse of Pepper, I knew he was going to be mine and come home with me, and then I fell in love with him afterward. But I didn't really have any time to get to know him beforehand like I had with both Auggie and Pepper. I had seen photos but they weren't full of personality like even Auggie's early photos are hahaha. We drove up to see him, I saw his temperament for myself, and I signed the check and he came home with me... and before that I had actually been keeping myself from getting attached, so... yeah.
