My 7 year old Holland Lop suddenly lost use of her fore and hind legs. On Sunday I noticed she was leaning to her side and a fecal mass was protruding from her tail. I cleaned her up and when I put her in her cage she fell over her on her side. She urinated twice (milky) and pooped (normal pellets). I was able to get her to a vet Monday and they ran multiple tests (x-ray, ultrasound, blood work, urinalysis, etc) and we are now waiting on the results. One thing that worried me was her urine sample was a thick, dark brown. She is on antibiotics, pain medication, and critical care. She is more alert but she still can’t use her limbs and is flopping over. I am constantly readjusting her to get her upright. Vet think it’s either a UTI or a uterine tumor (no evidence of tumor on the ultrasound). Any advice from owners who have experienced these symptoms?
