What this symptom means clinically

Prostate Enlargement is hyperplasia or enlargement of prostatic tissue under sex-hormone stimulation, increasing gland size. An enlarged prostate can compress the urethra or rectum, changing urinary resistance, urination frequency, or bowel habits.

🐱 In cats

Prostate Enlargement is relatively uncommon in cats; if suspected, further testing is usually needed to rule out other causes.

🐶 In dogs

Dogs, especially intact adult males, more commonly develop benign prostatic hyperplasia related to androgen effects, which can cause obvious gland enlargement.
