[swwatch]

Ok so 3 months ago, I moved into my first own house since my husband passing away 4 years ago. and i have a yard and fenced it in I also have a 200x 40 run for the dogs to do there business in.. it was all mud and weeds so me thinking im some sort of genius decided to have 7 yards of smooth river stone delivered and layed it in there run.. Well they hate it.. its like they are walking on eggshells in there and I feel like an idiot and created a torture chamber in there potty house.. LOL So today I will be out there shoveling rocks and i need another source of flooring.. i dont want concrete padding.. be to expensive for me.. Any suggestions? something reasonably priced and will keep mud factor down ???? and easy to clean up there stuff LOL?? and most of all comfortable for them to walk on?
