this is a cross breed - spaniel cross. I did the 1100 visit ouside - took him a few minutes to realise what I wanted - but then that led to an accident free night so pretty good going.
I agree that it depends on the breed. My boy was clean almost straight away, but the bitches My 3 year old took almost a year before she was completely clean (both day and night :( ) Her daughter was clean at 5 months. But then I was up more often through the night and let her out when I got up so she was used to waiting ;)
Our lab can go 8/9 hrs not that i've ever left her that long but she will wait on in there if its raining, in the end we have to thro her out into the garden, awful arn't we !
My Shar Pei will go out for a wee at around 9pm - he then goes to bed and gets up around 7am - never ever asked to go out in the night. I have trained him well!
Our Bernese can go about 2 days , not because we want her to but because she wouldnt pee in a strange place when we were on holiday- she must have a 4 gallon bladder !
