Indeed our one year old Jack named Mia is the friskiest little alpha female I've met yet! And we swear she sits at the end of our deck, watching birds, squirrels and chipmunks skitter through the trees around and near our backyard garden just wishing she had wings to fly up to the trees and get on the hunt! She's already proved to be a good mouser with 2 notches in her collar and she loves chasing bugs and bees! Unfortunately she also managed to catch two young sparrows through the course of the summer - she does have a love for hunting!
One thing I can say, it's a wild and crazy kinda place in the garden with a slew of puppies running around! We have had to adjust our garden to keep them away from plants that might make them sick and protect the plants from being trampled. Fences had to contain the garden and then we learned we needed to raise the height of several fences because Mia can jump 5 - 6' when she's got a good run at it! She has escaped several times on us and we've had a few good frights. Truly, it's as if Mia has wings sometimes the way she leaps and jumps - spring-loaded terrier.
That speed and stealth helps Mia when she's playing with Daisy who is now three times her size and out-weighs her by 60 some odd pounds at least! Because they've been together since they were both young they love each other dearly and while they tousle and growl and grab each other by the ears they have a ball then plop down together for a good nap or a good chew on their rawhide sticks.
I love the playfulness they've added to the garden! Once I get the lawn replanted things will look a little better but grass is something that grows fairly easily so I'm just waiting for the pups to settle down a bit before we expend all the energy to get a lawn going again! Maybe another year or two before we go to the effort of adding top soil and sod. It's the easy way and does work better then trying to re-seed a lawn with dogs running around!
