So the vet just called me, no UTI in Hugo's wee, everything looks perfectly normal which is really good news.
I have stopped using the crate as no matter how small I make it he will mess it and sit in it. Yesterday I came down to puppy covered in poo and wee. I don't want him to get used to lying in his mess so he's now in an x-pen for room to go if he needs to away from his bed. He even messed in the little carrier I use for the car when he had just been out to potty. I think he's getting so worked up about being stuck in such a small area that he voids from stress. He is happier in the x-pen and will probably have a fair few accidents in the coming weeks but I think this is the best solution for him.

She has full run of the house and doesn't normally chew things that aren't hers so this was a little surprising and very disappointing. Her access to the lounge has been denied now whilst we aren't in there, too many chewable things for her in there!
