Hello, I’m so sorry about your pup. It’s a bit unusual for them to develop cancer unless it’s a venereal disease. We would need more specific information about a urineanalysis, cytology, surgery report and bloodwork to give you a better idea as to what may be going on. However it sounds like what you really need to determine exactly what is going on and what type of cancer she has if any would be to pursue further care with an internist or an oncologist. Speak to your veterinarian about a referral to see an internist. Again it’s a bit unusual for a dog this young to develop cancer in the bladder. A very bad UTI may indeed cause some cysts vs cancer will typically cause more solid tumors. We hope you can get further answers soon, best of luck.
