Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with today. I do apologize that your question was not answered before (This was due to the expert you requested not being available).
Again I do apologize that my colleagues could not aid you sooner, but can you tell me:
How long has she been showing these signs?
Any history or falls, traumas, or injury?
Are her gums pink or pale/white?
Any changes to her breathing?
When you press on her abdomen, is she tense, tender, or sore?
Any changes or pain when you examine the feet and legs?
Has she been passing normal urine, feces, and eating/drinking?
Any chance Jill could have eaten something she should not have (ie string, plants, bones, toys, etc)?
