Ok I just have to ask what your husband did before he retired? And yes he has to much time on his hands so tell him to go into the office and start creating...then trademark the idea and make sure the pads are done in wild colors...I "for sure" would buy them.
I hate the white with blue ones...just remind me of hospitals.....and besides it would be so much more fun to look at a clown face and you are right..maybe more people would get into jeering their little ones on if you made a game out of it...You are seeing it with your own dogs...
This is how great idea's start...especially with a retired husband...
