High-Pressure Laminate Flooring
There are two types of laminate floors, and high-pressure laminate (HPL) is the most durable. This is especially beneficial if you have a large dog, since it means the floor can take more abuse. Also, according to Find Any Floor, "The best laminate flooring... (has) an Abrasion Class (AC) Rating of AC3, AC4 or AC5."
Direct-Pressure Laminate Flooring
Direct-pressure laminate (DPL) is less compact, and less scratch- and abuse-resistant than HPL, but if you have a smaller pet, this is probably the better option. Like with HPL, it should have an AC rating of 3, 4 or 5.
Although laminate flooring has some distinct benefits, such as being durable and relatively less expensive than some other types of flooring, laminate flooring is easily damaged by liquid spills that sit for any length of time, such as pet urine. Liquids can seep into the seam in the floor, causing bubbling and buckling. Some have had the best luck with vinyl floors. However, if you feel inclined toward laminate flooring, HPL is best for large dogs, and DPL is best for small dogs and cats.
