A doe in labor may need assistance if the kits are large, there are many kits, or if the labor is prolonged. A normal delivery should not take more than 30 minutes from the time the water sac appears until the last kit is born. If your doe shows signs of discomfort and straining for more than an hour with no progress, or if she gives birth to only one kit, she may be experiencing complications and will need help. Complications during labor are relatively common in rabbits, so it's important to be familiar with the signs and what to do if they occur. Some of the most common rabbit labor complications include: Uterine inertia: This is when the doe's uterus fails to contract properly, preventing the kits from being born. Uterine inertia is most likely to occur in does who are obese or have had large litters in the past. If your doe appears to be in distress and is not making any progress after an hour of straining, she may be suffering from uterine inertia and will need veterinary assistance. Fetal dystocia: This occurs when the kits are too large to pass through the birth canal easily. Dystocia is most likely to occur in does who are overweight or have had large litters in the past. If your doe has been straining for more than an hour with no progress, and you can see one or more legs protruding from her vulva, she is probably suffering from fetal dystocia and will need veterinary assistance. Prolapsed uterus: This happens when the uterus slides out of the doe's body through her vulva during labor. It is most common in does who are overweight or have had large litters in the past. If you see tissue protruding from your doe's vulva, she has prolapsed her uterus and will need immediate veterinary attention. If your doe shows any signs of distress during labor, it is important to seek Veterinary Assistance as soon as possible to avoid serious complications for both mother and offspring.
