I contacted the trainer and she said that in her opinion, Chloe wouldn't do well in the class because she will be on leash the entire time and she "doesn't want me to become frustrated". IMO, If I've put up with this ever since I got Chloe, I don't think I'm going be blowing my top off because she's still growling at other dogs. Of course, I also told her about Chloe's resource guarding over extremely high value objects (bones) and how she sometimes doesn't like to be physically restrained, but oh well. Maybe I should have kept that to myself as I'm working on both of them and we are making progress.

She recomended that I take her to Purdue's Behavior Clinic (I live maybe 30 mins away from Purdue, if that). In order to get in to the clinic you need to have a vet's "letter of recomendation" (LOL I don't know what else to call it) and then the consulation is 2 hours and is $220 bucks. The follow up visit is $80. I'd really not like to spend $300 on a behaviorist, espeically if I have a chance of working out her issues at my own home.
Besides that, I don't want to have to get Chloe tested for any medical reasons behind her issues when I know full well it isn't medical. When she tried to bite my sister and I a day after she pulled a muscle in her neck, now that was medical. But I don't think growling at other dogs while onleash is cause for a full blood panel to be done.

I do know some people with Greyhounds, but they aren't very Greyhound like. LOL They are both retired racers, but one thinks it is a watchdog and the other is very skittish. For intial training, I might use Blackie (as he is good with Chloe, for the most part) and then progress to Rose, as that is who Chloe focuses most of her "rude" behavior towards. Then we'll move towards some neighborhood dogs that Chloe knows, and lastly strange dogs that she doesn't know.
