Seriously, I really do only treat with kibble, because when I leave the house she gets a kong filled with yogurt, peanut butter and cheese. I don't want to give her too many extra calories. We don't walk all that much, probably less than thirty-forty minutes a day because she does have a large yard, and lets face it, a culdesac neighborhood is not all that interesting.
I can't agree with you on spiders, because as long as they are outside, I like them. I will however take your other suggestions under advisement.
