I wonder if he's self medicating? If you google dandelions you'll find they help with all sorts of health problems for both humans and dogs.
Glad to hear Bailey is back to his normal self and hope you get to the bottom of whatever is causing his problems. X
This is what I thought. He hasn't eaten so many today, but they seem to have put a spring into his step, he has being running around like a puppy again!
My dog LOVES dandelions. When I'm weeding I leave a few for him to eat after I've rooted them up. He eats ALL of them, top to bottom. If I could just teach him to root them up himself I wouldn't have to weed. Kidding, even when I weed and leave a few out it's not all, only a few.
