I have had laminate all thru my house up and down except kitchen and stairs for 5years now.
The kitchen did have laminate but Pippa as a pup pee'd so much it warped and i have replaced with ceramic tiles so if she pees it just mops up.
I have had no problem with scratches or slipping from Pippa but my lab Jake does slip on the odd occaision that he decides to try and run indoors
maybe to do with his sheer size??????
