I'm not sure if my breeder crate trained Momo at all - but she is wonderful! I thought she was going to howl all night - the first night she was there. Nope! About 10 min and she stopped. Every other night or time I put her in her crate it's 10 min or less. What a wonderful dog she is! After reading about doggies that have problems with the crate - I feel truely blessed.
That's not to say that she actually likes it... but you know...
