Hi all, I am after some advice. We have just brought home a puppy from the RSPCA, they think he is about 8weeks old, but have no idea what breed. His name is Barney. I have read lots of internet sites and a couple of books on puppy's and we have decided to crate him at night. We have a small back porch between the kitchen and the downstairs toilet and have placed the open crate in there with some paper on the floor and then made a sort of stair gate out of trellis so he only has that space to roam in, He whined for the last 15 mins and now it has gone quiet so i assume he is asleep. Am i ok to leave the crate open so he can to the toilet in the night or should i be closing the door and just letting him out when he wants to go to the loo? I am just worried if i do that i won't hear him when i go to bed. We have 2 cats, the older one doesn't seem to bothered by him, however the younger 8 month old kitten has been hissing and spitting everytime he comes near, she has now scarpered in to one of the bedrooms and we haven't seen her since. Barney starts barking with a wagging tail every time he sees the cats. do you think this will change? Thanks in advance and sorrt for the long post.
