[Birth of a vital puppy following prolonged whelping in a Labrador Retriever].

An 8-year-old primiparous Labrador Retriever bitch was presented to the clinic 46 hours following the delivery of 2 vital and one stillborn puppy due to an increase of vaginal discharge. At the veterinary clinic, the dog spontaneously delivered an additional healthy puppy without any obstetric support. The findings of the general and gynaecological examinations as well as results of blood analyses were within normal limits. This case shows that extremely prolonged whelping process may be a rare but possible phenomenon in bitches. However, it is recommended to re-evaluate dam and fetuses regularly in case the inter-whelping interval exceeds the normal time span in order to recognize further signs of dystocia and induce obstetric support when clinically indicated.
