Our smoke detectors go off so often when the oven is on that our dog now paces, pants and clings to us when she smells something baking. Perhaps it’s time to consider cleaning my oven…
I have no idea how I managed it, but my dog and I have a routine when I get home: she’ll greet me, tail-a-waggin’, but there’s no contact until I go into the bedroom. Then I stand at the foot of the bed as she jumps up on it and “hugs” me (paws on my shoulders, chest to chest, resting her 42 pounds on me while I pet her and nuzzle her face). It lasts for a few seconds, then she jumps off the bed and is ready to be let outside. We do this whenever I’ve been gone for what feels to her like a long time: whether it’s been 9-10 hours while I was at work, 4 hours while I was out with friends, an hour while I was at the grocery store, or 20 minutes while I was shoveling the sidewalks. grin I love our little ritual!

In the mornings, when my dog hears me stir my coffee, she starts to head to the front door, cause it means we’re going to people watch on the front porch. Same thing when she heats the cocktail shaker in the evening.
We once had a pet goose named Genghis that was “bowl trained”. As you may know, geese are vegetarians and he loved leftover salad, tomatoes, even green onions. He naturally assumed that every bowl contained salad fixings. One time we had some leftover chili beans with hamburger that I thought the chickens might like so as I was crossing the field to the chicken pen, Genghis trailed along insisting on checking the bowl out, so I let him. He gobbled a big bite then had a fit trying to spit it all out, flinging chili beans all around him. Have you ever heard an outraged goose telling you off? He carried on for quite a while and I had the impression that he thought my wife was a terrible cook! 
You are not alone in this! (one of the all-time laugh-til-you-wheeze threads)
OMG, Mama Zappa, thank you for that link! That thread is from a year before I joined, so I’d never seen it before.
