My personal favorite
Here are all the canine related ones I could find. I skipped a few toons, avoided putting up comics I've put up in the past, minus a few of my favorites. Click to enlarge and enjoy!
Although I never saw it, there was a "The Far Side" TV special back in the day. It aired on CBS and was fairly "Riss-kay" at the time. Haha! Here's a link to a semi-dog-realated clip of that special.
Extremely funny dark-comedy, as usual! I need to find that special in it's entirety.
