Things are going great! We love him. :)
When we took Beau home, he was pretty apprehensive about our cat, Babou (obviously frightened of him), but within ten minutes of Babou walking up to him over and over again, with a friendly tail-up approach, he warmed up to the cat! Within minutes, they were playing together. It's amazing, and we think our cat probably thinks he is a dog himself.
We decided to rename Beau-- now calling him Mana (which is Hawaiian for power), and he's been answering to that name well. At home and at my workplace we're working to housebreak him, which is going slowly since he already was pee-pad trained (he tends to pee/poop in the area that the pee pad is-- but also mistakes white sheets/blankets for a pee pad). He's started on a leash and today did AMAZING on a walk to the store. After a lot of positive reinforcement, he answers to "Mana" and "Let's go!" and will hurry along beside me while we walk. So far he also knows how to sit, and our next goals are "Wait" and training him to sit at crosswalks (or, asking him to stop and sit when we stop during walks -- he stopped and sat at 3 of 5 of the crosswalks we encountered today).
He's also been absolutely amazing with new people. My first day of work that he tagged along, he met all 6 of our restaurant's cooks and 4 different servers. He's so cute that when I take him out, we get stopped frequently by people wanting to pet him or know what breed he is. At first he was a bit startled and shy whenever someone new kneeled down to pet him-- but two days after tagging along with work and positive encouragement when a stranger approaches him, and he's now friendly with pretty much everyone he meets on the street (after an initial tentative sniff, of course).
Overall, he's loving, super smart, and an amazingly well behaved puppy. We feel blessed to have adopted him, and know that he'll keep growing and learning. He's somewhat attached to me, and if left un-leashed at my workplace he's constantly on my heels.
I think, personally, I have a lot of questions about Jindo breeds, what he could be mixed with, and how that might affect his breed-specific behavior later in life-- but regardless, we love him. And we're really happy to have chosen to adopt him. :)
Let me know if you need anything else! I will definitely keep in touch via the FB group. :)
