scared aggressive fearful groom on poodle maltese mix haircut

this pup was a rescue from an abusive home she was kicked out of a few grooming salons no one could groom her she came in severely matted yes you don't see this i thought my camera was on recording but realized later it wasn't she was unable to be sedated due to health issues ... **disclaimer** if your not a dog groomer this may be are to watch for some as she was very fearful i was no way harming her and when you see me put my hand to hold around her neck my thumb is under her chin and this is to prevent her from biting the scissors or myself no extreme pressure was done on this pup ive always been told i look heavy handed i think its just bc my hands are fat lol i swear im gentle Products I use on a day to day basis AMAZON PRIME MEMBERSHIP - (30 DAYS free) Smock/Jacket Says Professional Dog Groomer r Brush Chris Christensen Big G Dog Slicker Brush - Chris Christensen Dog Brush, Mark I E
