I’m sure that could be! Is there a way to prevent him from getting to the pool or trying to limit him from drinking it? That said, most dogs actually will eat grass. It’s somewhat of a myth that they only eat it when they’re sick. Every one I’ve known just seems to like doing it. Libby and my friend’s Goldens eat it like they’re cows
But I do think his stomach could definitely be upset from the chemicals! And/or he may just have gotten a bit overzealous and eaten too much grass
could be a combination of both.
