Plain-English summary
A 13-year-old male border collie was brought to the vet because he was having trouble urinating, with symptoms like frequent urination and a weak urine stream. X-rays showed a hard mass near the base of his penis that was pressing on the urethra, making it difficult for him to urinate. The vet performed surgery to remove the mass, which was diagnosed as an ossifying fibroma, a rare type of tumor. After the surgery, the dog was able to urinate normally again.

Abstract
A 13-year-old, 25-kg, castrated male border collie was referred for evaluation of pollakiuria, stranguria, and a decreased urine stream. A calcified periurethral mass near the caudal aspect of the os penis was identified on survey abdominal radiographs. A retrograde contrast urethrocystogram demonstrated that the mass was compressing the penile urethra. The mass was surgically resected. A histopathological diagnosis of an ossifying fibroma of the os penis was made. This report describes an atypical presentation of a rare tumor, an ossifying fibroma, that caused a urinary obstruction in a male dog. A review of the incidence, histopathological features, and behavior of ossifying fibromas is included.
