Thank you Mary.
I'm glad that you commented on on how she greeted the dogs, I was wondering about it. She is always very jumpy when meeting them. I'm glad to here that she is greeting right. Hoping to renew my library card and get books on dog body language to learn more about it.
I have a video of Missy walking a good bit behind another dog when I upload it would you mind looking and telling me what you think about Missy's body language.
Always very happy to help you Danielle in any way I can

Watched this video again and was once more very impressed with all your hard work. Missy is still just a smidgeon nervous, barely anything at all, just her ears went back when Copper (I think I have the right one here) did the butt sniff intro, but nothing to worry about, she handled herself with dignity and aplomb!
When Copper (right dog for sure this time) came up behind her and you 'warned' him, Missy walk on totally undisturbed!
Also, don't forget, you had both dogs
on the lead whilst Copper and friend where
off leash, always a much more 'threatening' situation to any dog! Missy (and Piper) handled themselves extremely well, especially as Copper seems a bit OTT with the butt sniffing etc. Very proud of you and Missy, again congratulations on all your hard work, it's sure paying off big time.
When you upload of course I'll look and let you know what I see.
Also, there are some very good sites on line with doggy body language, will check those out, as I know it's hard to get decent books etc.
