My Rudy & Lucky are crated while were @ work. The longest the've been in their crates @ one time is like 5 hours. Then my husband stops home during his delivery work and lets them outside to do their business and get a drink inside. We do give them a treat before they go back in their crates. Then their back in their crates till I get home. We don't leave any food or water in their crates for them. Rudy is 2 years old and Lucky is 4.
Lovemyalfie, I know other's might not agree with this. But we've done this since Rudy was like maybe 12 weeks old. We never had any problems, health wise or peeing or pooping in his crate. Good Luck.
