Is it bad to use dettol anti bacterial wipes on your dogs paws?

My friend uses them on her dogs paws and face all the time and she's always taking him to the vet because his paws are obviously getting irritated and hes chewing/knawing at them, causing open cuts and leading to infections. This is a constant cycle and she is so frustrated with him. Its that bad the vet has given her a repeat prescription for pain medicine. She also uses dry teabags on his face to 'clean' his eyes???? Does anyone have any information on this subject before i confront her? I know its not good i just dont want to say to her as were relatively new friends and she lives 2 doors down from me so i don't want to sound like an asshole if im incorrect. To add, the dog is a yorkie so its hypo allergenic they have super sensitive skin...
