Thanks for the advise and prayers guys. I took her back to the vet for a check up on Monday but this time see a different vet, as my regular one Dominic was off for the day, after inspecting Poopy she tells me that she has it in both knee's
but the left leg much worse than the other. She advised me to call back on Tuesday and discuss this with Dominic my regular vet. I did so and Dominic confirmed that she would need surgery, so she is booked in with the Consultant on Friday and then surgery hopefully next week at some point. So ill let you know what the Consultant says then.
