2017/10/13 Update: Konbu has been adopted!
Konbu is about 4 months old, and nearing 8 kilograms. He came to our house a week ago, and we will foster him for a few weeks until the next foster family can take him. (He'll soon outgrow the size limits for our apartment.)
He lived in the wild for the first month or two of his life, so he is very frightened of almost everything! But he has chosen our couch as his "safe zone". He won't sit on a lap, though he likes to lay next to us and lean his head on us. If we are downstairs, he prefers to hide under the bed. At night he sleeps in a dog pen in the bedroom - he doesn't whine, and he waits patiently for us to let him out when we wake up.
Konbu has learned to sit on command, but he is still unsure of my motives. He thinks I'm going to grab him, so he sometimes cringes from the hand that offers the treat. He has learned to sit patiently while I eat, as long as I reward him with a treat after I am finished eating.
He always uses a pee pad indoors, though he sometimes hits the edge, so I always supervise him so I can clean up. He also likes to chew on things, but he is easily distracted from chewing my belongings if I give him a toy instead. He loves his toys! If he has a lot of energy, he tries to sprint back and forth across the room to tire himself out. He occasionally gets excited about his food or toys and gives a bark or two, but I can distract him by inviting him onto the couch for a quiet cuddle before playing with him again.
He is just starting to walk on leash without pulling so hard. The beginning and end of the walk are very scary times for him, but in the middle of the walk, he is happy and prances with his tail up. He is mostly afraid of other dogs, but he has begun to let some of them exchange sniffs with him. He doesn't like it at all when people try to approach him. He was okay walking in the rain, until I opened my umbrella! Terrifying!
To sum it up: He's scared, but friendly, and making progress.
