Carrabba Mushroom Farm??

Whenever it rains, we get lots of things growing around here. Of course the grass grows, the trees grow, the garden grows.....but we also get MUSHROOMS!!
There are white ones, yellow ones, orange ones, brown ones, grey ones, even one that looked purple! They are all over our property! The dogs like to chow down on them whenever they are out in the yard, so we have to keep the dogs penned in whenever we have a crop growing (the dogs tend to throw up---no other serious problems, thankfully) We don't want the dogs to eat the mushrooms, but it is impossible to prevent that when they go out where the shrooms are growing!!!
