How can I repair discoloration on my floor?

It is more than likely caused by your dog eating cookies there! You could buy a stain stick/marker for wood and carefully touch up the edges. You might consider a rug for this area if this is where your dog likes to have snacks!

Hi! I would give your pup their own rug --- make it a washable one -- to just throw in your washer/dryer.

You might feed your dog elsewhere, where it cannot damage the floor. Both suggesting a doggie rug are on the right track too. Or maybe a rubber mat like they have to cushion your feet while standing.

Is it buckling? that is often caused by moisture.

Dogs lick and bite areas where their treats are so more than likely it is happening because of your precious pooch.

Just take a damp cloth and wipe up the area each time and use Bona laminate/stone floor cleaner once a week.

Hi! I agree with the others that it is moisture causing your problem. Since it is unlikely your dog will want to move, a rug is probably your best option.

In the pic it looks like the flooring is buckling. A good way to tell what is causing this problem, is to use an old toothbrush and try to brush up any crumbs from dog treats. If you don't get any crumbs, then it is more likely a moisture problem.

You can make a simple platform to raise the dogs dowls off the floor.

We bought the boot mat from IKEA to put our dog bowls on. I would be concerned that moisture is trapped under and causing damage to your subfloor. We just recently replaced our flooring and found a huge problem.

Could be the floor beneath is buckling. You might have to remove the whole floor to fix this.

Looks like moisture damage. Others have given good advice. When something like this happened to me, it turned out the dishwasher was leaking from the bottom and moisture was getting under the boards. Check any and all plumbing in the vicinity. You can try putting a mat/rug on it if you know what's causing the moisture.

Did you have a moisture barrier under the floor when it was installed? If you have a concrete slab it is imperative to put a moisture barrier. Other than that is your house foundation secure. Here we get cracks in the foundation. If it is a new floor I would call the installers.

If that is buckling, there is no fix, you have to replace. Once laminate starts buckling its the only option. Its probably from your dog licking. The doggie rug suggestion is the one I'd follow. It'll hide that little spot and will keep moisture from making it worse.

Check for moisture. We just had a similar problem. Turned out to be a leaky dishwasher.
