Ever hear of Soft Paws? They are little plastic nail caps meant for cats so they won't scratch the furniture. You super glue them on and replace them as they fall off. They actually really do stay on!

Chances are that JJ was never taught not to jump, and I doubt Grandmom would be consistent in training her anyway.... just an observation I made from seeing the older folks in my classroom. They desperately want to stop a bad behavior but can't seem to bring themselves to be consistent about stopping it. I have a lady now with a 12 week old golden who offered her to me last week (and trust me I was soooooo tempted to take this puppy!) just because the girl nips. They are NOT doing what I told them to do about nipping, and its only going to get worse from here as the puppy grows bigger and starts jumping and pulling on the leash.

Anyway, IF you think grandmom would be 100% (not 95% or 98%, but 100%) consistent in training, I'll write a short novel here about stopping jumping.
