I have an 8 month old puppy who is pretty much housetrained. We still have the odd accident but that's usually our fault i.e. the other night I took her out at 9.30pm for a wee but she didn't have one, husband was supposed to take her out at 11.00pm but as she was sleeping let her be and of course she did a wee at 2.30 in the morning! Apart from that she has not had an accident indoors since the end of August.
However apart from that she is very good and has never wee'd on anything other than the floor.
Last evening, she wee'd on our bed - it was really weird she had been out for a walk only an hour before and had wee'd twice on the walk. I was in the bathroom with my daugther and I could hear the pup running round like a loon, came out of bathroom to find a huge huge puddle of wee on our bed and wet muddy footprints all over the floor - why on earth did she do this?
