I have 2 toy poodles almost 2 yrs old. The female is potty trained and lets me know when she needs to go. The male will pee on the carpet if not let out every 1-2 hours. He will also hide and poop if not being watched. Shouldn't he be potty trained by now? I hate to have him in his crate when I can't be in the same room as him. My next move is to buy diapers. Any advice?
