I believed that hunting traits can actually intensify when we breed for them and if we constantly select for the most hunt in every breeding within a family...same with grit...Some folks will tell you that a dog can only pass what is in them genetically and maybe that is true...but it has been said that when left to mother nature the dogs will evolve to an average, so by selecting one can manipulate mother nature and this will intensify and purify the desired traits...
at one I saw a higher level of grit in some of my dogs towards the end as well as hunt until heat stroke because I bred for more hunt and more grit...not all dogs but it kept popping up and in reality these type of traits will eventually breed out because both of these traits can and will get a dog killed thus taking him or her out of the breeding program...
the intensifying in hunting traits is only a theory of mine so...don't take it as fact...just something to think about...
I am of the same mind on this. If phenotype can be set by breeding pattern, so should working traits.
