I probably should have gone into more detail.....
She is always very
people friendly and okay with some dogs. She's a 2 and a half year old spayed lab/pit. (I'm familiar with the pit side. I had a boxer/pit several years ago.) I also have two other dogs. I took her to our local Woofstock (sort of a dog fair with vendor booths, a concert and such). She was absolutely wonderful. Walking around the area, like it would be if we were on a walk, she was fine. But when it's just the two of us, she's different. Pulling, growling, barking, and she's very, very strong.....so much so that if I miss that first second of trouble, she's nuts. I use a prong collar that will have almost no affect until she starts calming after I pretty much sling her around. (as a last resort) When I see a dog approaching, we cross the street, or make a u-turn, over and over again....depending on the setting. I try to be very calm and do my best not to send off any vibes that would trigger her. She gets so focused that she is very difficult to redirect. When it's possible I give her lots of treats and I might say "look a doggie". In our SUV, she'll be in the wayback and if she sees a dog I say that again and toss handfuls of treats back there over my shoulder while driving. (I must look awfully silly) There's always a bag of treats on the passenger seat.
So......knowing her background, do you think that being around others for hours at a time will help to desensitize her? She's been to one well established and large daycare site a few times, for daycare and once being boarded for 2 nights. One of the workers told me that when she would first arrive she would "posturize" with some dogs. He said usually with the cranky ones that always do that. They would do some growling, wrestling, some drama, but no blood. The difference is, with me her reaction seems so much more extreme than two dogs approaching each other with hackles up, etc, sizing up each other then moving on. I don't know how far she would go. I'm sure I've left out some important details but I guess my initial question should have included this info.
Thanks for your time.
