Does it matter where the dog sleeps, in regards to training them? The first few nights, our new pup slept in our bed (thats where our oldest sleeps). However it was too much and we got no sleep as we refused to let her down incase she went potty. So, we started putting her in her cage at night to sleep. Overall, she's done well (she never cries when she goes in). One morning however she did poop (but she was in there all night long and a bit longer in the morning than usual as I had to tend to my son). She occasionally pee's in there too. Does anyone else put their pup in a cage at night?
