Interesting! Thanks for sharing that simple solution. I have noted my dogs vomiting occasionally and could tell they had an upset stomach. It is quite common to see both the dogs and the cat self medicate by eating certain grass. I've always observed that tendency in our pets from I was a child, so we tend not to worry too much unless things look serious and as if they aren't doing too well. Even then the first aim is to try and figure out what could be causing the problem. At one point we realized that frogs were cooling off the dog's (one dog at the time) water pan and whatever it left there would irritate her. We'd wash her pan and set clean water everyday and set it at a height she could reach, but the next morning the water was all dirty and yucky with frog poo and sometimes their shed skin. Sugared water... Interesting!
