Nineteen embryos, seven pregnancies, one female beagle ... scientists say procedure could save endangered species and prevent genetic disorders
From the paint on their toes and the tips of their tails, the puppies stand out as unusual. But the litter of seven will go down in history for more than the colours that tell them apart. Now five months old and doing well, the dogs are the first to be born through IVF.
The healthy delivery of the dogs by caesarean section on 10 July marks a success that has eluded scientists for 40 years since efforts began in the mid-1970s. The procedure could transform attempts to save endangered dog species, and potentially help prevent the genetic disorders that afflict so many breeds.
