It depends on what your hunting preference is. Some people are dog hunters, some are not. If I could I would even hunt sprang lizards with a dog. I just enjoy hunting with a dog more than still hunting.
As much as I love eating squirrels I don't really worry about killing more. I love being out in the woods watching my dog work. As far as killing squirrels though, I have seen when still hunting was more productive. I have also seen it more productive with a dog. I would still rather be out with a dog. Just my preference.
I’d say that’s the way most experienced dog men feel. I have easy hunts occasionally but I question my sanity for hunting a dog more often. I can kill far more with far fewer headaches without a dog involved.
