My Bolognese is making strange little gurgling sounds in her throat and sticking her tongue out at a certain pace. It seems like hiccups, but I want to be sure. She ate some peanut butter and a tiny piece of a treat and swallowed both without a problem, but she won't drink water, won't do even simple tricks for more treats, and is currently just lying down in a corner (she was sitting all hunched up before).

It's a little late so no vets are open right now. /an/ advice?
