Another vote for Crate Training.. A close friend is a vet.. and you would not believe the near death surgeries she has had to perform on young dogs that injest something in a "puppy proofed" room. Crates are safety zones for the puppy and help them develop skills needed to be a good citizen the rest of their life. Do they like being locked into a crate the first few times... HECK NO.. and they can sound like caged monsters in there.. but before long, they willingly go into their little saftey zones. I cant imagine why a pup would need more room than a crate would provide, when most of the time they spend in the crate is sleeping... I have a 9week old right now.. after the first day.. she is quiet in her crate, and is either sleeping or chewing on a nylabone puppy chew ( a crate safe toy- nothing stuffed in there) and has only once peed in her crate. She comes out ready to play and run, but has no issue with the crate come bedtime.
