Sundae seems weak in her hind end and seems to have a lean/tilt to one side... this happened quite abruptly. It's hard to pinpoint exactly when, as we were at the cottage and I don't see her move around as much (they aren't allowed out for floor time indoors there, which is when I really see them run. They do get wide open spaces outdoors there, but mostly just graze and eat the grass and do very little running around.) As far as I can pinpoint, it started abruptly a day or so ago. She is able to walk, though she looks a little wobbly doing it. She doesn't seem to be uncomfortable, is eating and drinking normally and is behaviorally very normal. I will contact my vet in the morning, but any ideas or feedback? All I can think of is a stroke or a back injury of some kind, but she has not been active enough at the cottage for me to imagine how she could have hurt herself, and she certainly doesn't have any pain or agitation when we touch or palpate her back or hips. Is there anything I can do to help her out? She is about 6.5 years old, so she's an elderly girl.
