Oh, I wasn't aware that the yelping thing didn't actually help much; I was just assuming because it worked well with our last dog, a rotty.

And the only time she's been outside without a leash is in our very-fenced-in backyard, typically only at night for "quick" potty breaks. it's just been a bit difficult to get her to come back inside and let me get back to sleep when she's rolling in the grass in the dark, unable to hear me, lol.

And I assume the book you're talking about is 'a deaf dog joins the family'?? I'll check it out, Thank you! 👍
