yeah fair call Nekhbet. My girl was 18 months old when doing this as no other method was working. 18 months old is old enough to read your dog and know how she is going to respond, so in that sence, this method worked well for her and me. As for a 5 month old, yeah, maybe not such a great idea. And as Nekhbet said, it is a negative training method. But at the end of the day, if my dog isnt jumping and putting dirty/muddy feet all over my white shirts, im happy.
Kiki, maybe use this idea as a last resort when the pups a bit older!
