Hello I am Dr. Joey. Thanks for trusting me to help you and your pet today. I am a licensed veterinarian with over 16 years of experience. I look forward to working with you.
I am so sorry she is experiencing this, and on a holiday. I am very worried if she is still unable to stand up and walk. There are several possible causes for this ranging from a back injury (ruptured intervertebral disk, inflammation, infection), anemia (so internal blood loss such as from a bleeding tumor/mass or even stomach ulcer, although you should notice very dark/black stool if there is bleeding in the digestive tract), toxicity (unlikely but on the list), bloat or flipped stomach, and the list continues.
I wish I could give you something easy to do at home but this is one of those situations that calls for an immediate emergency veterinary visit for an exam and likely some testing to determine why she is painful and not walking.
I am at a point I need to know what questions you have. I hope that the information I provided has been helpful.
Please let me know if for any reason you need further clarification, have more questions, or were expecting a different type of answer.
If you received all the information you needed, then kindly submit a rating.
