i would use a detangling spray douse the area well .. let it rest a couple mins.
then with a FLEA comb brush it out .. hold the strands that are tangled by the base so as to prevent from pulling from the root .. then slowly try to comb it out .. it will take a while and u may need to stop for a bit b/c he will get fisty.. it hurts .. if worse comes to worse just clip it off..
let me know how it turns out
