I just got a newly neutered young adult about 24 hours ago. Zero marking thus far because when we come back inside the house, the belly band goes right back on before the leash comes off. When we go outside, leash on, belly band off then outside we go. It's a slightly bothersome but mindless routine that I/we will do for at least a week. LOL Just teaching him the ROUTINE, "No potty in the house!" Outside potty "good potty", inside potty "NO!"
We'd still be on the first pad except I forgot to take the band off once when we went outside, oops, didn't realize until he got to business.
