Which laminate flooring is good for pet with accidents?

Hi I am considering replacing living room carpet with wood effect laminate flooring due to bad damage by dog’s urine. I would like to find out if anybody has experience with dogs that tent to have accidents and if that damages the laminate? Is there any laminate flooring at reasonable price that is waterproof? I have found waterproof laminate but it is far too expensive for me at around £49 per square meter. The area that I need to cover is 29 square meters. Any suggestions or advice would be greatly appreciated.
