I have a little balcony in my apartment, and when the weather is nice, the first thing I do when I wake up is to open the door to the balcony so that Rosie can go outside and sunbathe. She loves it, and often sits out in the sun while I go about my morning rituals, waiting until I finally grab her collar to head outside for our walk. Sometimes, though, leaves fall from the trees near me and land on the balcony. If I am not paying attention, Rosie will often eat these leaves. Within about ten minutes of eating these leaves, Rosie will vomit them back up.
There is a big elm tree in the dog park, and if I'm not paying close attention to her, Rosie will eat the leaves and vomit them back up. In the fall, I have to take paper towels with me to clean her up, just in case. She's not the only dog I know that vomits from leaves, but its pretty rare. I see lots of dogs eat these leaves and do just fine. Rosie, however, spasms and hacks and pukes. She looks extremely unhappy while she's doing it, and even shortly after, with strands of yellow bile hanging from her lips. I clean her up, and I clean up the little puddle, and when I finish throwing out the paper towels, what do I find? Rosie eating more leaves.
