We brought home the foster. She'll be here til a week from Monday. She's beautiful; a lovely caramel brown thing. Probably rat terrier, but I'm not a breeder. She's incredibly timid and clearly not used to being on a leash--she completely balks every time I try to lead her anywhere, goes spread-eagle immediately.
Her name is Gracie (which I also find adorable).
Will post pics soon.
To train her to be OK with the leash, for a while at least, give her doggie treats (the 'quick-eating' kind, not a bone or something) just before... then during putting the leash on. Wait a bit before you try to move with her on the leash, and give her a treat just before you say something like a questioning, "walk?" Then, if she goes spread-eagled, put a treat on the floor just a TINY bit out of her reach, wait for her to get it, then put another one down a tiny bit FURTHER out of her reach, etc., until you can get her almost to walking speed.
Obviously you know pets well enough to be talking to her very calmly while you attach the leash and ask if she wants to walk, but the treats may go that extra bit to getting her to associate walks with good things. [Possibly she was abused by a prior owner while on a leash.]
I hope that helps.
I actually used a slightly similar process to get Lucas to sit still for his nails getting clipped. I gave him treats
right after clipping his nails, so he associates sitting still for that with getting treats. Now, most of the time, he'll sit upright on his butt on my lap (tail down between my legs), almost like I'm cradling an infant in one arm. He usually doesn't struggle, he just looks up at my face almost constantly during the procedure (though as soon as I finish the VERY last nail, he squirms a lot to get down). As soon as I set him down he gets almost a meal's worth of assorted kitty treats (about six to eight each of five different flavors of treat = one very happy cat

). I also talk calmly to him while I'm doing the clipping. Held so close to my chest, the vibrations from my low voice probably feels like I'm purring to him.
