My guys are all 100% except I do have to watch Bobbi for marking when a girl is in season but then that is the price you pay when having a stud dog in the house with them. They all have different ways of telling us when they need to go out. The only time we have ever had accidents was when someone (young son) didn't let them out and I wasn't home. I don't count that and I know the dog would have had to go very badly to go inside especially after being trained. But that hasn't happened in so long I can't remember the last time.
My guys also wont go in an x-pen let alone a crate. At the JRTCA Nationals once, we set up a couple of x-pens together around a tree. They wouldn't go, had to take them out and potty them.........poor guys had to power pee the first time when I realized they wouldn't go in the x-pen, never made that mistake again. Poor Bobbi had to pee for so long he almost fell over and got tired of holding his leg up!! Bad me for not realizing sooner.
Who at almost 5 months old is almost completely trained, at the trial this past weekend she was great and she does let you know when she needs to go out. I am happy that she will 'go' while on leash, which never happens at home, so the only time we get to practice that is at the few puppy classes we went to and two agility trials.
