So my Ruby (approx 8 months old) has been having what I think is blood in her urine for almost 2 months now, and she has been to the vet twice - two different docs - one gave amoxycillan, thot it might be bladder infection, amoxy did nothing. Next doc gave Baytril and its been 2 weeks since that and still she has blood in her urine. What should I ask vet to do next? Ruby is otherwise happy as a clam and eats all her food, drinks water, cuddles, plays etc.
