Veterinary questions? Ask a Vet for Answers ASAP
Hi, Welcome to Just Answer. I'm Chris, a small animal Vet based in the UK. I am reviewing your question and will get back to you as soon as possible
Sorry to hear about this problem with Bella. I need to ask a few further questions in order to give you the correct advice. What breed is she? Has she had any kind of accident in the past 24hrs? Are her legs splaying out sideways or is she 'knuckling' on her paws at all?
Pain can sometimes cause reduction in appetite and water intake and swaying or loss of the control of the back legs suggests that there could be a neurological problem here.
One of my concerns would be Intervertebral disc disease (IVDD), otherwise known as 'slipped disk' in her spine, this can put pressure on her spinal cord and cause problems with coordination in the back legs. In mild cases improvement will be seen with rest and anti-inflammatory pain relief, however more severe or progressive symptoms can need surgery. There are also other possibilities and a full veterinary examination will be required to gain a proper diagnosis so I think she really does need to be checked over by a vet at the earliest opportunity so the correct treatment can be initiated.
I hope that makes sense? Please let me know if you need any further help or advice.
