Do you go to dog parks? Do people clean up after their dogs?

Our dog park has become so bad that I can't even take my dog anymore. I don't want to make a big deal about any of this if it's a normal thing and we've just been lucky until now.

I get that dogs eat poop, but this is all my dog does at the park now, then he comes home and throws it up.

He loves the park so I really want to bring him back, but we can't right now.
