Hi there, I'm Deb, a licensed veterinarian.
Look at her rectal area - any swelling or redness or discharge? It's very likely that Becky needs her anal glands expressed, or she has an anal gland infection, abscess or impaction. Below is a link for information on a dog's anal glands. Anal gland issues can cause her to bite and lick at her rear end, and feel poorly, such as a decreased appetite.
This is something that can wait until tomorrow, rather than have her seen on emergency tonight.
But, if this is keeping her up, restless, aggitated, having her seen tonight would relieve her discomfort.
O. K. We hadn't thought of that. We'll give it a try. Thanks!
You are welcome
