I concur that he was a jerk. But he might have had his own dog's safety in mind when he said it and I can't blame him for that. I'll just take her earlier next time. Less dogs and less people. As she gets more familiar she will probably get less defensive. Which considering how shes acted in past interactions with dogs (nearly took me off my feet) I think she did quite alright today. Baby steps...
I totally agree with baby steps. I had a chance to see her pic, she's a pretty girl!
I think dogs are like having toddlers, they're a full time job. The rewards are so great though, and sometimes rescues can be the biggest challenge since you really don't know much about their past.
Good luck, I hope you can get to the point that she can be off leash and get out there to run and play!
