Why is my dog with Cushing's peeing inside? Is it a UTI or behavior?

I am sorry that Trixie is not herself. Cushing’s disease is a hormonal disease that typically occurs in middle age to older dogs. These are the clinical signs of cushings; https://www.petcoach.co/article/5-common-signs-of-cushing-s-syndrome-in-dogs/ If you are noticing troubling issues with Trixie such as pain when urinating, difficult urinating, changes to drinking behaviours. I would advise a return trip to the veterinarian as a possible infection of complication from her surgery may be present.

Poor Nemesis. Sometimes pets will need the medication adjusted. I recommend to call your veterinarian and ask if another test is needed to evaluate the blood levels in his body. The test is called an ACTH stimulation test. It has been found that 50% of dogs with Cushing’s disease will also have a urinary tract infection that can only be detected with a urine culture. I recommend to have this test done as well as this will cause constant drinking and urination. Other conditions such as thyroid disease, diabetes or kidney disease can also cause these signs. You must start ruling them out. Best of luck.

This sounds like it's more likely to be behavioral, from your description - but if it's a recent change for Chichi, it's always a good idea to have a urinalysis done just to make sure. If any evidence of infection or other abnormalities are found, your vet can start her on appropriate medication to treat the problem.

At her age there are several things it can be. Your vet can collect a urine sample to check for a urinary tract infection. They can always draw some blood to check her kidneys and blood sugar and for Cushings disease. All these can cause an increase in drinking and urination which will lead to accidents. If all of that is normal, than she may be getting incontinent and they have medication for that also!

If she is getting recurrent urinary tract infections than she should be checked for bladder stones as dogs with bladder stones typically have recurrent infections. Your vet can take an x-ray or do an ultrasound of her bladder to check for stones. She should also have her kidney values checked and may need to stay on an antibiotic for an exteded period of time. Call your vet and schedule an recheck. Hope she feels better soon!

A UTI is always possible, and it's always best to bring him to the vet or bring in a sample of his urine in for testing if you suspect that may be the case and to rule out any more serious health issues. Stress and anxiety (especially if the storms are bringing thunder) may also be causing him to hide or not want to go outside. Looking into something such as a thundershirt, playing a soothing radio station or talk show, distracting with treats or puzzle toys, and taking him out when there are breaks in the storm may all help him relax a bit. If he is very distraught, talking with your vet to see if medication to help him relax would be useful is another option.

Cujo is such a cutie. Congrats on adopting an adult dog!! If this was a one time event, I would just monitor him. He definitely could just be getting used to his new house and routine. However, if he has any further accidents, if he starts asking to go outside to urinate more frequently, if he strains to urinate at all, or if there is any blood in his urine , I would have him evaluated by a veterinarian right away. They will do a urinalysis to screen for an infection likely and may do other tests based on results such as x-rays to look for bladder stones.
