Hi Jorge! So nice to hear from you. I'm sorry Chuckie is having problems...I'm not sure if Chuckies bumps are like some Jake gets from time to time..but I give him a nice bath with a surgical soap..like hibiclens. Then at least once a day I use Maloket or duoxo wipes on the bumps. It really helps Jake. But I'm pretty sure his come from environmental allergies. Good Luck!
