Annoying Boxer habits...
Zoe eats soap. When I open a new bar, the wrapper must go in a trash bag, out to the dumpster immediately, or the dogs will knock over the trash can and chew on the wrapper. Zoe just goes straight for the soap bar. They both love (loved) bubble bath too.
Crumb Jowl Kissies - big drink of water, then eat some dry kibble, making sure the crumbs stick good, then lay your head in Mom's lap, or on her sleeve. They only do this when I wear black. How do they know???
Murphy's Law of Dogs - your dog will only poop in someone's yard when the home owner is watching. If you are walking at night, the dog will only poop in a well-lighted yard. If there is just one unscooped mess in your own yard, the dog WILL step in it.
Wanting to go for a walk, at 4am, or 5 minutes after returning from one. Zoe's collar hangs on the basement door. She will poke it with her nose when she thinks it's time for a walk.
Butch used to bark once to go out/come in. Neat, simple. Zoe never did figure it out. She stares at me to go out. When she's ready to come back inside, she kicks the storm door. So there's a huge Bang, the house shakes. Oh, Imperative Girl must want to come in...
