Friend, I am sorry for the delay; I had some technical problems at this end.
In response to your question, in a male dog with symptoms of increase frequency urinating
can be caused by: A urinary tract infection, bladder stones, prostate disorders (infections, tumors
, enlargement), etc. to name a few causes. To determine the exact underlying cause he will need a hands on examination, urinalysis and xrays as initial screening test. Treatment will be based on exam and test findings. This is not an emergency, it can wait to see your family veterinarian. If at any point he is unable to urinate, that would be an emergency as it suggest a possible stone block the outflow of urine in the urethra; he should be seen by ER vet in that case. For now, observe him follow up with family veterinarian.
