SO sorry for your dog. Right now, all we have are cats, but we've raised mini pins before years ago. They really become part of the family.
On your band adjustment.......you're doin it wrong. lol The proper method is tighten it down TIGHT with a small wrench. 5/16" I think it is. I believe the book spec is in inch pounds.....but I remember working it out and it was 8 foot pounds. That's good and tight with a short wrench. The reason for that is to get ALL the slack out of the band before making the adjustment......so you might be ending up a little loose. So tighten it down GOOD with a small wrench and make the 2 turns out. Or 1.5 or whatever you do. I always go 2. Just some FYI.
