There are going to be many breeds of canines that are demanded by consumer markets. While commercialism may inform these, more often than not there is a prevailing system which is tasked to make everything in these markets more relatable. This is in terms of breeding and genetic health, which are items often connected to great dogs.
Dogs enjoy some status after they have won skills or talent contests in dog shows. Thus Champion Labrador Retriever puppies may be available for those who want them. The development of champion lines could really work for those who want to breed their dogs reliant to how these could have excellent qualities they want.
These qualities could help form teams of performing canines specially bred for their skill in performance. This means that there may be things which are going to make them special. These could include their knowledge of orders or commands and how they respond or act quickly with their special intelligence.
Champions are not more about sports here, because there are really no acceptable sports involving canines these days. Dog fights are illegal, and racing only uses Greyhounds, but Labs themselves are often domesticated or working canines. These are pets who have their own specific jobs in the home or in farms.
The skills of those who have been trained since they were puppies for performance can be translated or given to their progeny. However, such skills may be a matter of training for each of these.
But then the champions themselves may also have exceptional intelligence and physical qualities that are readily transmuted through breeding.
Thus bred from sires or dams who were chosen for their fundamental qualities have something to offer enthusiasts. These may not want to use the qualities precisely for what they had been bred for. But knowing the capacity or capabilities of their charges in this sense could also be useful in other ways, such as the capacity to be trained in guard duties and even real K 9 work.
Good breeding is not a thing that requires genetics to be effective. However when this is coupled with things like intelligence, the value of a puppy goes up. The records can tell all sorts of great detail about beings who have won their share of championships or dog shows and these all could be something which is naturally in demand.
Most of those who have their own domestic animals know how the stock of any of their animals goes up when the bloodlines are excellent. The dogs though are not defined according to how they have been bred for sports. Shows are not really sports, but they will tell how one canine is actually more intelligent than another.
This has been the key to some lines going through runs that involve generations being great performers. When it comes to shows there might be a real item about bloodlines that could be relevant. There will be other stuff that makes for better lineages too but there is always something mystical or just favoring those judged excellent.
