There are modern and iconic breeds of dogs that are getting more popular nowadays. These are the so called designer breeds which have made broad inroads into the popular imagination. But there remain many kinds of canines which are rooted in tradition although in their time they were also new to the scene.
The history of humanity connects to lower species which have been domesticated through thousands of years. The Cavalier King Charles Spaniels puppy is in fact the product of a few decades of experimentation with other breeds. This was a few centuries back, which in the time scale of millennia is relatively short.
The dogs themselves have progressed with humanity and the Cav is one of those which have advanced the process. In fact, it was more or less one of the best results of genetic experimentation that produced a well made type. The geneticists in dog breeding have carefully nurtured the line and continually protect it from inbreeding.
Thus you can have the healthiest pups of the breed these days. And that means getting the documentation or papers for these. When they have papers you can have these bred and sold more expensively as compared to those pups that have no papers, but the usual thing for many is to simply have recognized member of the type.
Although the geneticists frown on the inaccurate use or even breeding of these pups and mating them with other kinds, there is not stopping those of freer bent. Some exclusive circles of course will have the original qualities of this kind of canine. But they are in danger of inbreeding always because no new strains are injected into them.
That is why the designer kinds might be preferred nowadays because healthier lines are needed. And for dogs this means a lot less health risk and may even spell progress. This needs to be studied well because the animals themselves may not really be benefiting from an age old relationship.
People say that humans do not really see what they are doing to species which are close to them and this could hold true for the most loyal of companions. There are issues with the Cavs that may mean that the time to rethink and move on for this and other breeds. So owning one may be important these days for simply monitoring the line.
Breeding should be a cultivated thing although again mongrels are often the healthier in comparison. So there is going to be a movement sooner or later to reform the process for all kinds. This could take some years or even decades for the obvious effects are seen.
Perhaps organizations like the AKC is aware of this and thus sponsor and support the designer types. The movement is flagging though after some years of trending popularity. But there might be better mixtures which are being developed and these may soon come into the markets but many hope that there are still many qualities related to the old breeds.
