The prostates of 30 not castrated old dogs with or without clinical symptoms of prostatic disease were histologically evaluated. It was observed the incidence of possible changes in the gland. Among the changes, benign prostatic hyperplasia (BPH) was the most common diagnosis, accounting for 85.6% (n=24), followed by chronic prostatitis, 64.3% (n=18), dysplasia of the glandular epithelium, 42.8% (n=12), atrophy of the glandular epithelium, 39.3% (n=11), focal inflammatory infiltrate, 25% (n=7), focal glandular dilation, 21.4% (n=6), acute prostatitis, 7.1% (n=2), squamous metaplasia, 3.6% (n=1), metastasis of systemic neoplasia, 3.6% (n=1), and prostatic abscess, 3.6% (n=1). Because the lack of symptoms in most of dogs with prostatic changes, the specific clinic exams in routine, as rectal palpation and ultrasonography, are very important to early diagnosis and treatment of dogs with prostatic disease.
