The old black lab at a nearby house has had hip surgery at least once, and is getting very elderly, although they continue to strew the yard with stuffed toys for her: most recently a warthog. She's apparently been having a rough go of it recently: two days in a row I've seen one of her people holding her up with a cloth sling while she does her business. In the rain, with an umbrella. I hope the dog feels better soon; she's very well behaved. And I'm sorry for her people.
