Dog owners – what’s your biggest problem with your dog right now?

I'll go first:

My Malinois is 3 years old. Dumb as hell but loyal.

Anything that moves she barks at. People, bikes, other dogs, plastic bags.

She's been through professional training twice, but nothing. It's driving me a bit crazy at this point and I'm losing sleep.

Drop your problem below maybe someone here has already cracked what you're struggling with.
