Did I do the right thing???? Help! Kinda long

OK here is my situation. I work at a Dog and Cat boarding facility complete with grooming and training. One of the trainers is overly aggressive toward the dogs he trains. What I mean by that is he is very abusive!!! Before I started there I heard form another employee that he got mad at a little dashound, yanked the dog up by the leash and began to strangle it!!!! The manager caught him but only told him to calm down.

Recently I have observed hiw he treats his clients' dogs. For one he keeps them cooped up and tiny kennels with no water and he doesnt let them out to go potty. The dogs can be there form 7am to 5 pm!!!!
Also two days ago a groomer witnessed Jeff (the trainer) abusing a german shephard by slamming the dogs head in between a door!!!! She told the manager but nothing came of it.

Jeff IS a good traner as long as the dogs he's working with don't make him mad. He also brings in alot of money which is one reason why I think he hasnt been fired.
This guy is so cicoky and rude!!!!
Well today I went to the human society and complained about him and come to find out the officer told me he's had alot of other complaints against him!!!!
I remained anonymous the whole time. I just dont want to see these dogs being abused like that!!!! Did I make the right decision telling somebody about all this??? I think I did.
I feel so bad for all the people that are having their dogs traied by Jeff!. I wouldnt want my dog abused like that I'm sure none of you would either!

Sorry I had to get this out!!!
