I'm taking him out more often to avoid in house accidents. Still urinating frequently, but holds it during the 4 or 5 hour between trips home from work. He is urinating less since the antibiotics, but not back to his usual routine. Throughtout this situation he has not got me up to go out at night (7 - 8 hours). He was neutered at 6 months of age.
As I mentioned in my initial post, the infection and white / red blood cells are still present in his urine even after two courses of antibiotics.
Our vet has suggested the urine culture in a few days after being off the antibiotics along with an ultrasound of his bladder.
He had total blood work a couple months ago before he had his teeth cleaned and it was within normal ranges all around.
My vet is in Sarasota Florida and she was named one of the 100 Best Veterinarians in the US. I have 100% faith in her - yet I'm petrified he may have cancer and die.
His other medications are Atopica for allergies and Benedryl for scratching. He has inhalation grass allergies.
