Welcome! I am Dr. Altman, a licensed veterinarian and happy to answer your questions today.
The possible differentials for Alli are going to include a urinary tract infection, kidney infection, kidney disease, bladder stones/ crystals, diabetes, or even a bladder tumor. The highest probability of diagnosis in a dog Alli's age (in order) are going to include a urinary tract infection, diabetes, bladder stones/ crystals, kidney disease
I would definitely advise collecting a first morning sample tomorrow before your appointment (First morning is best because it is the most concentrated, based on a 12 hour fast so protein of the diet does not effect the results, and often the most telling sample of the day). If more than an hour old please refrigerate the sample in a tupperware container but reading it quickly (within that hour) after collection is preferred to reduce the risk of creating crystals/ casts while sitting
Please let me know if you have additional questions regarding the information I have provided today
The likely tx. given her age, of 4 in order you listed for 1st two; Urinary tract or diabetes? Can a dog tolerate concentrated cranberry extract in the amount of 1132mg tb. Does it matter I am more then an hour away from the vet closest to us, so if I collect, then have early apt, I can take a cooler for the sample per your recommendation, is this correct. Is there a risk for dogs for untreated urinary tract infection, do they clear up on their own?
Thank you for your help and found this very helpful.
