I got Bella has an 8 week old puppy but I only worked part time so the most she was left in her crate during the day was 4-5 hrs. It was always clean. Even at night when we crated her for 8 hrs. the crate was clean in the morning. I am a firm believer in crate training until you can be sure your dog understands what is acceptable behavior (not just where to potty, but what to chew and what not to chew). My ex-daughter-in-law had a Pekingese who, at the age of 2-3 yrs. old, was going potty in the house occasionally while they were at work. I suggested a crate and that was the end of his accidents. He kept his crate clean through the day and he was not a puppy learning something new. He was about 3 yrears old and un-learning bad behavior. I too agree that an older dog might be more advisable in your situation. Good luck and please keep us up to date on your search for your new best friend!
