I stand by my recommendation, it is based on experience with a lot of shooters and much personal experience with . 22 pistols carried in the field on a daily basis for years (starting at 12 years old). You have to have the gun with you if it is going to do any good, people "in general" are much more likely to carry a small, light, easily controlled handgun on a day-to-day basis.
If you can get the bullet into the right spot, a . 22 will get the job done on a coyote. Generations of sportsmen and hunters have carried a . 22 handgun on their hip with plenty of confidence all over the USA, and there's no reason why the lady who asked this question can't as well. I generally carry a much stouter weapon for 2-legged varmints, but I wouldn't worry at all about carrying a K-22 for use against the 4-legged types.
As an illustration of the fact that size of the gun ain't everything, here is a nifty Usenet newsgroup message I read several years ago and saved for just such an occasion:

Easily the best collection of statistics and stories on the subject of
ammunition effectiveness that I've found is 'Handgun Stopping Power' by
Evan P. Marshall and Edwin J. Sanow (ISBN 0-87364-653-3). It lists
statictical summaries of thousands of gun fights broken down by caliber
and specific cartridge and has many brief descriptions of representative
events too. In the section on the . 45ACP they include this one to
illustrate the point that there are no magic bullets and that shot
placement and luck count for a lot too:
"The rooming house residents had been arguing all day. Finally, two of
them had tradded blows and vowed to go get their guns. They met in the
hallway. One was armed with a Government Model Colt loaded with hardball
while the other had a cheap . 22-caliber revolver. Our . 45 lover laughed
and opened fire. After he emptied his gun, he looked in amazement as the
. 22 carrier pointed his small revolver at his chest and fired once. The
auto dropped from his hand and he died. "
"The . 22 carrier went to his room, changed his clothes, and then took
two different buses to the hospital, where the doctors removed seven
rounds of . 45 ball from his chest. "
So what conclusion can we draw from that one? Well, other than to
avoid arguments, the only general principles that I can see are to always
take careful aim and to always have exact change handy for the bus.
Get the book. It's just packed with fascinating stuff.
