Is that a Norfolk? My Westie used to give chase to anything in sight that wasn’t human. He even injured a cat once but not because he bit it, he chased it off a 2nd floor balcony and the cat jumped, landed on its feet and just kind of limped away. Poor kitty. But he has killed mice, squirrels, possums, always chases cats. But like some terrier breeds he will not chase down birds. He seems to like hangin’ with the sparrows and the starlings and the jays. And they like him around because they know he keeps the cats away. Will chase pigeons tho’. I notice now since he has turned 10 y.o. critters will come into our yard and he is happy to just hang and watch.
Australian Terrier and if he wasn’t so cute I’d of killed him. I’m spoiled because our other dog is a German Shepard. So our family has an Einstein and a kid with ADHD.... the Shepard is smart as heck and the Aussie is a killing little thug, but so spunky and cute. It always needs to be at your feet touching you. very cool dog. The Shepard just kind of shrugs and I can just here her thinking, “ I could kill that , but I don’t FEEL like it.” hahahahaha
