Jack my lab/beagle boy would potty in his crate, most of the time just pee but sometimes poo. He did this from the time I got him (3 months) until about 5-6 months old. He was only in the crate maybe 4-5 hours a day but it didn't matter, even if I took him outside before I put him in there. I had to give him a bath daily. We think he was from a kennelled situation but he eventually learned to hold it in the crate but still hasn't learned to poo in the grass, he does it on the cement. Not to get off subject...she is too young and too small to expect her to hold it for an extended period of time, it will take a lot of patience and work....
