However, they are typically adopted by their foster parents who have cared for them during the reunification process. At Summit County Children Services, you must become a foster parent if you want to adopt.
And when I ask how long they've had the puppy, it's usually a short time like 3 or 4 days or maybe two weeks. It takes longer than two weeks (generally) to fully potty train a puppy. (Some do catch on much faster.) It's very simple to potty train a puppy, but that doesn't mean it's easy.
My Shih Tzus held it through the night fairly early, like at 3 months old, as soon as they were potty trained ;). Potty training was quick-1-2 weeks after bringing them home. They were in a crate overnight for the first month, so that helped. Your dog should be able to hold it for at least 6 hours overnight.
