Our Cav, Sophie, had diarrhea yesterday. Not terrible explosive stuff, just worse than pudding and clearly her intestinal tract is irritated. She felt fine, had appetite, wondered why I would not feed her, but she had to 'go' every four hours.
We're out of town today. When I dropped her off at our dog groomer to board, I gave her Sophie's cooked rice, explained about the diarrhea, etc. She has decades in grooming, previously showed the smaller size poodles, knows dogs more than I do.
She told me some of her dogs had diarrhea, too, and it is caused by the unusual extreme cold weather we're having. (It's really a lot like what you've got in the UK and Ireland. Highs of only 23F and lows of 15F)
Have any of you ever heard of unusually extreme cold weather causing diarrhea in a dog? I've had a dog all my life, but never experienced this before.
