Has any one had problems with dogs on laminate flooring? I am concerned about scratches and urinary accidents.

I installed about 200sf of Pergo Glueless floor in the kitchen of our new home before we moved in. I gave the floor about 2 weeks to acclimate, and used a good grade of pad underneath it. I spent about a week putting it in and made darn good and sure that I had a 1/4" gap on all surfaces. The install went really good and the floor looked great! After I installed the dishwasher, I noticed a slight crown on the floor. Double check and sure enough, the floor is buckling up. I'm devastated and angry. I spent so much time being deathly careful - making the proper gaps and all, and the floor buckles anyhow!!! :madhell: So, I suspect there could be one or several causes for my problem. 1. is it possible that putting caulk is the 1/4" gap around the sink caused the bind? The Pergo instructions said to caulk around the sink dishwasher, etc. 2. is it possible that the dishwasher caused the problem? I suspect this may be it. I ran the floor under the dishwasher - should I have not done this? Also, I had to jack up the back feet on the dishwasher to level it. It's possible that the outside of the DW is bound up on the underneath side of the countertop. I wonder if it could be jammed hard enough to stop the floor from moving? 3. Or, is it possible that a concentration of heavy appliances would stop the floor from moving? The range, DW and fridge are all pretty close together. All that said the biggest question is: Is it even possible to fix it? Once a floor buckles, are you just hosed, or will it go back down once the problem has been corrected? It would not be too much trouble to remove the floor from underneath the DW, so I'll try that first. Anyone have any experience to share? TIA, Joe Michel
