Sheep Trouble Urinating After Lambing: Causes & When to Call a Vet

After lambing, a ewe may have trouble urinating because the tissues around the vulva and urethra are swollen, bruised, or painful. This is more likely after a difficult delivery, prolonged straining, assisted extraction, or a large lamb. In some cases, the ewe is trying to pass urine but the stream is weak because the area is inflamed and sore.

More serious causes include trauma to the bladder or urethra, uterine or vaginal prolapse, and postpartum metritis. Merck notes that uterine prolapse in ewes is a true emergency and can occur immediately after or within hours of parturition, especially when the uterus has poor tone. In severe prolapse cases, the bladder may also be displaced into the everted uterus, which can interfere with normal urination.

A ewe may also appear to be straining to urinate when she is actually straining from pain, retained fetal membranes, ongoing labor, constipation, or uterine infection. Postpartum metritis in sheep can cause dark, foul-smelling discharge, depression, reduced appetite, and reluctance to nurse. Those ewes need prompt veterinary attention because infection and dehydration can worsen quickly.

Less commonly, the problem is a true urinary obstruction, including a stone or blockage. That is more common in males than females, but it can still happen. Any ewe that repeatedly postures to urinate and produces only drops, cries out, or becomes bloated, weak, or recumbent needs urgent evaluation.

See your vet immediately if the ewe is straining and not producing urine, has blood in the urine, seems severely painful, is down, weak, cold, or not interested in her lambs. A visible prolapse, a large swollen mass at the vulva, foul-smelling discharge, fever, or signs of shock also make this an emergency. Merck lists straining but failing to urinate, bloody urine, and bleeding from the urinary or genital area as reasons for immediate veterinary care.

You should also call promptly if the ewe had a hard lambing, needed traction, or has continued straining for more than a short period after delivery. Postpartum problems can overlap. What looks like urinary trouble may actually be uterine prolapse, metritis, retained placenta, or internal trauma.

Careful monitoring at home may be reasonable only if the ewe passed urine normally after lambing, is bright, eating, nursing, and has only mild temporary discomfort with no repeated straining. Even then, watch closely for the next several hours. If urine output drops, the abdomen enlarges, she isolates from the flock, or she stops mothering her lambs, contact your vet the same day.

Do not keep trying repeated internal exams or force medications without veterinary guidance. Extra handling can worsen swelling, contamination, and stress in a freshly lambed ewe.

Your vet will start with a physical exam and a recent lambing history. They will want to know when she last urinated normally, whether the birth was difficult, if there was traction or a retained placenta, and whether she is eating, standing, and caring for the lambs. A temperature check, hydration assessment, and exam of the vulva, vagina, and uterus help sort out whether this is urinary, reproductive, or both.

Depending on the findings, your vet may palpate the bladder, assess for prolapse, check for tears or severe swelling, and collect urine if possible. Urinalysis can help document urinary tract disease, and some farm vets may use ultrasound to look for a distended bladder, free abdominal fluid, or uterine problems. If hypocalcemia, shock, or infection is suspected, treatment may begin right away while diagnostics are kept practical.

Treatment depends on the cause. Options may include anti-inflammatory pain relief, fluids, calcium support when indicated, antibiotics for confirmed or strongly suspected postpartum infection, and careful correction of a prolapse. If urine flow is blocked, your vet may need to decompress the bladder, relieve the obstruction, or refer for more intensive care.

Your vet will also discuss lamb management. Some ewes can stay with their lambs during treatment, while others need temporary separation, bottle-feeding support, or closer monitoring for nursing and bonding.

If your vet says the ewe is stable enough for home monitoring, keep her in a clean, dry, well-bedded pen where you can watch urination, appetite, and lamb care closely. Make sure she has easy access to fresh water, hay, and any feed your vet recommends. Reduce chasing and handling. A sore postpartum ewe may stop drinking or nursing if she is stressed.

Watch for actual urine output, not only straining. Small dribbles, repeated posturing, tail lifting, vocalizing, or a tucked-up painful stance can all mean the problem is getting worse. Also monitor the vulva for swelling, discharge, bleeding, or a protruding mass. Check that the lambs are nursing and staying warm, because maternal illness can quickly affect them too.

Do not give leftover medications, attempt to push tissue back in, or perform repeated internal checks unless your vet has shown you exactly what to do. Fresh postpartum tissues are delicate, and contamination can make infection more likely.

If your ewe stops passing urine, becomes depressed, develops a foul odor, goes off feed, or seems less attentive to her lambs, call your vet right away. With postpartum urinary problems, early action usually gives you more treatment options.
