Finally got home from the vet half an hour ago. After feeding the babies and geting out of my office clothes (finally...ahhhh....long dayyyy), here i am, on YT (you think i'm addicted already?

)
Ayways. Apparently yesterday he was given a lot of water to drink at the hospital (to make sure he was not dehydrated from the walk the night before), then he was put on canned food (he eats kibbles, and sometimes homemade doggy food) so that was also some more extra fluids. And apparently he didnt pee yesterday when he was there. So they think it might be just a lot of pee that had been accumulated and needed to come out. I am gonna have to watch him for the next few days and see if any of the symptoms come back, in which case im gonna have to take him back to the vet immediately. Otherwise it's all good.
Lets keep out fingers crossed.
