A Stud Dog Unable to Mate After a Long Tie

by A reader

Reader Question
Our 4-year-old terrier stud dog was always eager to mate. In January he mated with our female, and they were tied together for more than an hour. Since then he hasn't been able to mate. He wants to, but his penis can't come out and he can't get an erection. His semen is fine, and our vet can collect it manually. We've tried with 4 females with the same result. Any ideas?


Answer from Our Team

Sudden mating problems after a long tie could come from an injury to the penis, the bone in the penis, or the sheath during the tie, pain (for example, from the back, hips or prostate), or a learned reluctance after a painful experience. Since collection by hand works, the problem may be pain, a narrow sheath opening, or a behavioral block during natural mating.

Ask your vet for a thorough exam of his penis, sheath and prostate, and of his back and hind legs, and possibly X-rays to check the bone of the penis. A veterinary reproduction specialist (theriogenologist) can help with both diagnosis and options like artificial insemination in the meantime.
