CaniLine – Breed Identity Analysis

CaniLine-pes

Did it ever occur to you to search for the breeds making up your mixed-breed pet? Or to have the origin of your purebred dog verified? Sometimes, things are not what they appear to be ... The test can differentiate more than 200 dog breeds shown in the list below, while the number of breeds is still being widened.

What are the cases where the CaniLine breed identity test can be applied?

- Dog’s breed purity verification

- Finding out the breeds making up a dog

Only some genes can be seen

It is very difficult to identify all the breeds that take part in the unique appearance and nature of a crossbreed; even professionals are only able to determine the parent breeds for sure in 25 %. In dogs, physical appearance is controlled by a small number of genes – about 2 %. It is quite important to understand the dominant and recessive genes. The recessive genes are those which need two copies (one from each parent) to show a trait, while one copy is sufficient in the dominant genes. The dominant genes, such as those for short black coat, drop ears or block head shape then take over the recessive ones, such as long coat, prick ear or tan points associated with certain breeds. Then, the observer would not even guess a breed whose characteristics are hidden under the dominant genes of the other parent. Some breed features, such as flattened face in bulldogs or extremely curled tail in pugs, only seldom survive the first crossing. Moreover, dominant features can be attributed to literally hundreds of different breeds in addition to those we take into account.

When crossbreeds are crossbred

It is obvious that the difficulty to determine ancestor breeds increases with every crossed generation. The more mixed the dog’s origin is, the more mixed and diluted characteristics would be in his or her genetic signature. In average, puppies obtain 50 % of the genes of either of the parents, i.e. 25 % from the grandparents and 12.5 % from the great grandparents.

It can very well happen that not two puppies resemble each other in a litter of two mixed-bred parents. Dogs of mixed-bred origin can differ considerably in size, shape, colour, and character. The different characteristics of their close relatives are the result of genetic recombination, i.e. the exchange of various DNA parts between chromosomes, which results in obtaining a unique DNA combination.

Dogs cannot speak but their DNA can

Three things are needed for precise breed detection: an extensive database of breeds, a sophisticated algorithm, and a great number of markers strategically located in the genome. The next-generation sequencing technique is used in testing. The CaniLine test establishes 1,877 traits in the canine genome. Such traits are then compared with the database of more than 200 different canine breeds containing over 12,000 samples, evaluating the conformity and similarity in the marker combinations of the dog being tested and of the breeds described in the database. This patented technology helped more than half a million dog owners all over the world to find valuable information about their four-legged friends and understand their unique needs.

How about the purebred dogs?

The CaniLine test can be used to analyse not only canine mixed breeds but also the pure breeds and to compare precisely through further analyses as to how consistently the dog’s DNA corresponds with that of other purebred dogs of the same breed in the database. The DNA profiles of certain breeds can differ in dependence on their family lines and their specific geographic origin. Different DNA formulas, for instance, have been found in certain purebred dogs in the USA, Great Britain, or Australia.

Test capacities and limitations

  • The test will establish the breeding history three generations back, which means that we can find the breeds of the parents, grandparents and great-grandparents of the dog being tested. The minimum contribution of the breed found is 12.5 %.
  • If a dog is made up of a breed missing in the breed database, it will be reported as a mix of breeds in the protocol. If you wish to verify the purity of a breed that is not listed, the test will most likely not provide the answer you are seeking.
  • If all great-grandparents are mixed breeds, it is not possible to establish the breeds making up the dog being tested.
  • The test cannot be used to validate pure breeding but to indicate a breed. If a dog has 7 or 8 purebred great-grandparents, the test will analyse to what extent the individual resembles / differs from the majority genetic traits of his/her breed.
  • The test cannot be used to envisage dog’s behaviour or aggressiveness. Every dog is a unique individual whose physical and behavioural characteristics are the result of several factors, including genetics, training, treatment, and environment.
  • Learning the unique origin of your mixed-breed dog will facilitate your understanding of his or her behaviour and nutritional and health needs. In mixed-breed puppies, the test can estimate their probable height and weight when grown up, which may help the owner to set an optimal diet and choose suitable food.

.

What do the test results include?

  • The test results include the percentage of breed composition in the form of a family tree of 3 generations and a pie chart. It makes it possible to find out the breeds present at the levels of parents, grandparents and great-grandparents. The parent contributes to the puppy’s DNA with 50 %, while the grandparent with 25 % and great-grandparent with 12.5 %.
  • Profiles of individual represented breeds.
  • Expected weight and size profile of the dog being tested.
  • In purebred dogs, individual’s similarity with the breed’s gene average is subject to assessment.
