General Health of Pembroke Welsh Corigs
Pembrokes are a fairly healthy breed, but as with all dogs (purebred as well as mixed), do have
some inherited problems. In a perfect world, the parents, grandparents and great-grandparents of
a litter should be evaluated for possible genetic disease. General information on Pembrokes
follows as well as a list of possible genetically transmitted diseases. For further information you
should contact your veterinarian and your breeder.
Lifespan: 11-13 years. Some Pembrokes have been known to live to 18-20 years old.
Males: Average onset age of puberty (6-8 months old).
Females: Tend to have normal length estrus (heat) cycle and gestation (pregnancy). Average one
heat every 6 months. Tend to be slightly older when come into heat for the first time (9-11 months
vs. 6 months for small breeds). Most are free whelpers (require no help at delivery) but increasing
numbers of reports indicate more tendency toward dystocia (difficult birth). If dystocia occurs, a
caesarian section is often required to save the life of the dam and the puppies. For this reason,
breeding Pembrokes should be left to those with the experience to recognize warning signs of a
difficult birth. No one wants to lose a loved pet and, if not recognized early enough, a dystocia can
result in the death of the dam and puppies. Some dams may be slow to remove placental sac or
to tend to pups.
Litter size: Average 6-7 (range 1-12)
Birth weight: Average 10 oz (range 6-18 oz)
Dewclaws: Remove all.
Tails: If not born with a natural bob or tail-less, dock as close as possible, but not so close as to
leave an indentation. Tail should not protrude beyond the anus (tail length must not exceed two
Ears: Usually become erect between 4-16 weeks. If not up by 12 weeks they should be taped.
