I am Dr. Snow, and I can try and help you today! I'm sorry to hear Roxy isn't herself. Is she limping at all, or does she seem unstable when she walks?
Ok I understand. The symptoms you are describing don't really fit with constipation. It sounds like she may have injured her back. Back injuries can cause them to be lethargic and seem painful but hard to tell exactly where. I would suggest strict rest for right now, and potentially having her see her veterinarian in the morning to maybe be prescribed some pain medication and do a thorough exam.
You're very welcome! Good luck, and please kindly rate me. :)
