You'd recognize bloat the instant you saw it. As long as she's acting normal in every other way, just keep an eye on her and don't allow her to do any strenuous exercise. If she's gorged herself on food, the increased possibility of torsion will be there until she gets rid of the swelling, which should happen any minute.

If she chewed up something non edible that she shouldn't have and swallowed it, she may have trouble passing it and become blocked. Keeping an eye on her is about all you can do for now.

If in doubt, call your vet!

Let us know how she's doing.
