I must say a huge thank you to commenters who pointed out that chokecherries can be poisonous to dogs after I wrote about Shyla gorging on them. I'd erroneously assumed that chokecherries are fine for dogs because bears and coyotes both eat them. Dogs are in the same family as those animals, which led to my false sense of security.
Here's an example of a bear scat at this time of year. It is composed almost entirely of chokecherry pits. And it's the biggest black bear scat that I've ever seen! That's my foot next to it.
After your comments alerted me to the danger of chokecherries to dogs, I searched the internet, turning up site after site that said that they could be fatal. I don't know how Shyla dodged that catastrophe despite having poop that looked almost like that bear's. But she did, and I am so grateful for it. Thanks to all of you, we are not allowing her to eat chokecherries anymore. That is a challenge, since the bushes are all over our land but we're managing to do it.
Over the past week, autumn has arrived, and Shyla is here to enjoy it. She loves the cooler weather. She dashes through the aspen groves in a picturesque way that causes me to pull out my camera.
