Well, hearing of a outwardly aggressive Possum (around these parts) is quite unusual. They usually hiss and take a defensive posture, but the many that have been through my yard, even little
Thor would run um up a fence/tree in a heartbeat.
I have a "resident" Possum (she lives down along the Bayou) who we''ve named Sweety
. I have food (scraps) and water out in the yard for it, and how ever many other strays are brave enough to "trespass".
Opossums are Nature's little Janitors. Anything that dies or is left by my two little Varminteers, is gone by morning. However, Sweety knows to come after 8PM, since I close the Doggy Door for the evening.
QuickSilver, My Female Becca (2yo now) was a one time quite reluctant to challenge Squirrels, Sweetie, the Lawn People (specially the ones with Weed Eaters). But, after being with My Male Sneakers for this length of time, She's literally a WARRIOR now. Nothing is permitted to violate Her territory, and she doesn't need any backup from the Male.
Much of the hunting and territorial instincts that our little Varminteers "could" demonstrate, is best taught to them by a more mature Dog. That and more is lingering in their breeding, just waiting for mother nature to bring it out. I'm very proud of Becca, She, as the breed goes, takes and active part in searching out Frogs and Snakes when we go "hunting" down along the Bayou. Both of them will eat what they catch (most of it and time permitting), and that is the only Raw I permit. I know where Sweety's den is, and I try to avoid that area, though My Male would like to visit her regularly.
I think with proper exposure/training, you would see that little
Thor would learn to use that natural Hammer he has. From my personal experience, a 4lb Yorkie, can whip a 10lb Possum, any day of the week.
I know this is somewhat controversial, but IMHO I believe our little Varminteer Warriors should be given the chance to do just that. Let them be Dogs.
