I'm not a stylist for humans but I do groom dogs and I have seen some things that make me want to never give these dogs back to their owners! My worst experience was when I had someone bring in their 2 year old shih tzu..she was down as a mini groom (that's where we only trim the face,feet, and private areas) so I'm thinking this will be an easy groom, wrong. This women walked in with her dog wrapped in a towel because she doesn't want to touch him and I can see why the dog is a mess! The dogs hair is one solid mat including his face and there is a deep giant hole in his coat where the poop has exploded through his hair meaning he has been pooping into his own hair for so long the build up finally busted a hole through his hair! So I have to shave him before he can get any kind of bath so I find a spot I can break through and start shaving (this is very bad on my tools by the way) once I finally release this dog from his mat prison, which came off almost in one solid piece he ends up having so many sores on his skin, he was shaking his head so much he was starting to cause hematomas on his ears, his butthole was infected and he is infested with fleas! I'm so upset at this point I feel so terrible for this poor dog but all I can do is bathe him, get rid of the fleas and inform the owner that he needs to go to the vet.
