Thanks everyone.
Camera is a Canon A620.
Yes, he is my first B. I lived with two dogs for about 6-7 years previously. Border Collie and Springer Spaniel.
He's doing ok today. He slept throughout the entire night without making a single noise. He is adapting to his wire crate extremely well. I put a fleece blanket in there for him to sleep on that will keep him warm. I was told he did not develop any chewing/destructive habits and I haven't personally seen anything yet.
He's still being very cautious of everything. I brought him outside to go (which he has been successful with every time), but once I bring him back inside he just wants to hide in a corner. I left some food and water out while I got ready for the morning, which allowed him to be by himself for a good 15 mins. He didn't really even move from his spot. So he is not eating or drinking anything right now. I know it's best to keep them on a schedule. If he doesn't eat in the morning, his next chance will be later this evening.
Any tips on helping him get more comfortable? I know it takes time, but what worries me is that he has 0 interest in water or food. I am using the same food he was fed with the breeder to keep things simple (then moving him over to a food of my choice).
