Now that I have both a TAG & a CAG, I am seeing some amazing differences in their traits. Other than the obvious physical traits (such as coloring and size) between a TAG & a CAG, they are different in many ways. My CAG appears to be more intellectual, you can see her mind working all the time trying to figure things out mentally, where as my TAG will physically try to figure things out by doing! Althiugh my tag talks way more than my cag, and has a much bigger vocabulary, I have found that my cag is content to just sit where ever I put her for a much longer period of time than my tag who constantly has to keep busy!
I do know that many will say it is a difference in personality, but I can see it is much more than that. I am curious to see if others owners of both species have seen such an obvious difference. I have only had my cag for a week, but I am learning so much from the subtle differences they have.
