Welcome to Justanswer! I am Dr. Altman and happy to assist you both today!
So sorry to hear Dreya is having issues with increased urination and blood in her urine. There are a handful of causes including:
1.) A urinary tract infection which is the highest possibility having a history of diabetes, sugar in the urine increases urine alkalinity and is a breeding ground for infection
2.) Bladder stones that traumatize the bladder and cause bleeding
3.) A bladder tumor, most likely in a senior pet
4.) Trauma- hit by car, muscle trauma of some kind
Ideally until you are able to get to your veterinarian, please increase water intake. You can do this by supplementing the dry food with water and flavoring the water (maple syrup for example) as well. Increasing the water intake will help "flush" out the bladder and reduce the pain associated with the bleeding.
You can purchase pet cranberry chews in this situation in hopes of reducing the pH of her urine but it is also been found to reduce the bacteria's ability to attach to the bladder wall. These are available at your local petstore.
Collecting a first morning sample in a tupperware container and refrigerating the sample if more than an hour old to have your vet evaluate the sample will help determine the cause of the blood in the urine on Monday morning.
Your vet will run a urinalysis, potentially do a urine culture to look for bacteria, an X-ray to rule out a bladder stone, and bloodwork to ensure there is not a metabolic cause or kidney issues causing the symptoms but also ensure that the diabetes is well controlled and not an issue for this new symptom
Diagnosing the issue will help determine how best to treat the blood in the urine to get your pet comfortable swiftly
Below is more information on this condition in dogs, called hematuria (blood in urine):
