Ask a Dog Vet and Get Answers to Your Dog Health Questions
My name is***** have been working in various aspects of small animal practice for over 5 years.
The large numbers of bacteria are definitely indicative of a bacterial infection somewhere in the urinary tract. We missing some of the picture here though. What were the rest of his urinalysis results? Were there white blood cells, red blood cells, ketones, etc...? Also, is he neutered or intact?
Got it. Thank you.
Ok. So his urinalysis is very suspicious for cancer or a significant infection. To be honest, it is quite rare for male dogs to get such a significant infection. Older male dogs that suddenly develop a urinary tract infection are not common. Generally there is some sort of inciting cause for the infection. The most common reasons for these results are : Prostate infection, bladder stones, prostate cancer, bladder cancer, urethral cancer.
I cannot comment on what exam your vet did but if this were my case I would be doing a good rectal exam to check the urethra and prostate and would be considering x-rays or ultrasound to assess the urinary tract.
You are welcome.
Yes, a good look from a pathologist may help figure things out. That is a great first step. Thanks for the update.
