Hi, I haven't had a dog since I was little kid and will be getting Sheltie this week. I prefer an older, but still young dog but after three months I met a 5 month old that was really sweet (he was more well-behaved than his great grandmother who was barking crazy). I'm reading a lot of posts on this forum but haven't come across one that's similar to my situation. 1) Should I still crate him at night? His first owner said he is about 85% potty trained. She let him out right in front of me and he pooped within two minutes. Is it better if I still crate him by my bed at night with its door closed? All the doors in my bedroom will be closed so he can't get into the bathroom or living room in the middle of the night. But probably not a good idea right? My bedroom is carpeted. If I should still crate at night, I guess I'll stop when he adapts to his new potty schedule. I was originally going to use carrier because they seem more versatile but apparently, they're not as durable as crates. 2) I will crate him at first while I am at work, coming during lunch to let him go potty and play with him inside my apartment. Generally, what is a comfortable age to start letting him have a run of the place while I'm away? I will monitor his behavior and dog proof the place as much as I can before I start doing this. I'm debating on putting him in playpen while I can't pay attention to him that much (chores, stepping out for a few minutes) until he's an adult. I'll also consult with current owner but I'd like to read some other people's guidance too. Also, she's going be really busy in the next couple of weeks. I also want to make her feel extra confident when I finally take him home. Any advice and constructive criticism are appreciated. Thank you!
