I have two harnesses that I love on Morgan.  
 
I have a step-in made by chattiesmom that i got at least 3 years ago.  Its usually what i put on her when we go for walks around the neighborhood. 
I also have a harness that i bought from a dauchshund rescue at a pet expo.  I believe it came from this site/rescue 
Hug-A-Dog Harness  I like this more then other harness vests because its sturdier, has a safety buckle over the velcro on the neck, AND (my favorite part) has a "handle" on the back for quick pick up.  I think its real purpose is for a safety belt in the care but i use it to pick Morgan up or put her down when we are out.  its great if you need to grab your dog really quick because a strange dog is headed their way or kids are running towards you to pet your dog.  The site has some pictures on it but i don't feel they do the harness justice.
