On cooler mornings I leave my office door open to the backyard. Chippy (my Westie)stands guard watching for squirrels or other offending varmits trying to hang out in his yard. When he does spot a squirrel he literally flies out the door and chases the poor squirrel up the tree. After this workout he is usually satisfied and comes strutting back to his perch just inside the door. We have our share of dog snot on the front window as well. For the most part, though, he spends his days peeing, eating, barking, sniffing and, most of all, sleeping (which is his favorite past time).
Our half Australian Shepard, Misty, also took a dim view of squirels and cats. She killed three of the latter, two by using our other dog, Maude, as a blocker, but fortunatly never could catch a cat.
squirel up a tree? I live in Cent. FL on 5 acres. Several winter ago we had 4 black bears in the backyard eating acords from the oak trees. My Doberman took after all of them (scared my wife and me to death), but she's fearless. She treed all of them in the oak trees. Now these are 400 lb. bears. They scramble up oak trees like squirells. We got her back into the house.
So your dog is a squirrel chaser huh? My dog prefered deer. My hubby would walk our dog into a field and it would be constantly filled with deer. Once he saw them, he took off like a rocket and chased the deer into the woods, come strutting back, and looking at my hubby as if he had done the greatest thing in the world. I always got a chuckle out of that.
