I would think I would try to be constantly aware of the old adage"You can't teach an old dog new tricks."
Also be cognizant some dogs are old breeds used for centuries for that one specific purpose, which still equals "old dog".
There is a whole world of study out there that will back me up when I state "there is a lot to be said about genetic propensity."
??? What. Lol, I don't get what your trying to say,
Should I get under 1yr old or older then 1yr old
