Why is my spayed female dog peeing blood? What can I give her?
If Lily is peeing blood, I would be concerned that she has a UTI, bladder stones, or even bladder cancer. Unfortunately there is nothing you can give her at home, she has to see a vet for this problem. If she appears lethargic, ill or distressed, or if the urine appears very bloody, then she should be seen by a vet ASAP. In this case, please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.
If she is otherwise healthy and happy, eats and drinks plenty, you can wait until Monday morning. Feed her wet/canned food, add water to it, and make sure she drinks a lot of water to help flush the bladder.
