Rain or hose,should do it.
Garden hose or sprinklers. I have 6+ dogs. I also trained them to use a certain part of the yard too, which makes it much easier to deal with.
I wait for rain or spray with a hose.
I’m the summer, it is hard to get that smell out. I try to saturate my dogs urine after he goes to dilute it. I also keep potted lemongrass and citronella around our patio, which keeps the smells away from that area
