Yes, dog paternity tests are now commonly done amongst our canine friends to determine canine parentage. Your little Lola may have had a liaison with 2 or 3 other dogs- so which one is the father of her puppies?
In most cases, dog breeders actually seek this type of test when they are unsure about which male sired a litter of puppies- you might ask yourself why this is so important – for a dog breeder it is hugely important in order to be able to provide the dog’s lineage to a dog buyer. The results of the test provide genetic proof to the buys who will want a guarantee of the dog’s pedigree.
So Canine DNA testing has changed this- whilst before it would have been impossible to know which dog sired a litter of puppies (if more than one male was involved) and breeders would rely on guess work, it is nowadays possible to pin point the biological father of the litter. By comparing the DNA of the puppies with the DNA of the dogs you suspect may have sired the litter, this type of canine test tell you exactly which male is the biological sire of the litter.
PCR – Polymerase Chain reaction for Canine Parentage
Dog DNA is analyzed using a scientific technique known as Polymerase Chain Reaction. Using an enzyme known as DNA polymerase which helps read the genetic code, scientists can then make thousands of replicas of the DNA with which to work. PCR has changed the face of DNA tests. Samples can be collected by the dog owner using a dog DNA test kit. Things are made more complicated when there is a case of a multiple sired litter or when the alleged fathers, so to speak, are brothers. But generally, determining canine parentage, even in cases where the alleged fathers are related, can still be done by means of a paternity test.
