Jimbud, either a S&W bulldog (you can shoot .38 or 357 mag) or a .380 auto or 9mm.
The reason being the bulldog is hammerless (good carry gun) and as Wheel said your wife could shoot the .38 with confidence. Kahr makes some nice concealed carry autos in 9mm and .380 as does Smith&Wesson. Modern autoloaders are very safe and easy to shoot.
Again with the 9mm or .380 your wife could easily shoot, and you sould have extra round capacity. If you can find someone you know that has a couple calibers you and the wife to try then find one at a shop that is comfortable.
Hope the dog is healing and the wife is emotionally better. Good idea on the class.
