I have two dogs who are 3 and we’re about to welcome an 8-week-old puppy on Saturday, same breed but a boy (my other two are sisters- breeder didn’t say we shouldn’t do this and we’ve been lucky in that they are lovely calm dogs and get along superbly with one ever so slightly more in charge) just after advice about night time toilet training. We crate trained the girls, and got up twice in the night to let them out, gradually cutting it down to once a night etc. I’m a bit wary of disrupting their routine with the nighttime training of the new pup, I’ve also read by 8 weeks pup could be capable of going from 12-6am without the toilet, is this true in anyone’s experience? Seems long to me? We have a very large under stairs area where my other two sleep, my plan is to put pup’s crate in front of the entrance to this, he will also have an attached playpen which the crate will open into. Then I was thinking of putting one of those artificial grass pee mats inside the playpen but (during the day I will be repeatedly taking him out to the section of our garden where the other two are trained to go) I was thinking that if I take him outside at 12am before I go to bed, then put him in his crate with the door open to so he can access the grass mat inside the playpen if he needs to at night, then husband gets up and takes him outside at 6am, that would be minimal disruption to the other two dogs, as I know if we come down to pup in the early hours the older two will think it’s time to get up for the day and will just whine and whine when we go back upstairs. Does this sound like a good plan or a potential disaster in training terms? Thanks
