I have two huskies. They never look guilty or sad, pretty much nothing. They were fighting over toys last night and I yelled at them. They stopped fighting but, nope, no guilt. There are 47 toys in the toy basket but they both want the ONE that the other one has, well in addition to the one that they want to keep. And my girl had been suddenly having "accidents" in the house at night, nope, no guilt there either.
My BF had a Corgi, she was Black and white and tan. She was really pretty and a great frisby catching dog.
We have 3; we miss our dog Max but enjoy the relative freedom of cats vs dogs. They’re all wonderful.
