Tudy asks you to make an effort. If not for his sake, at least for yours. And he reminds you that a dog in the house or at least in the yard can do wonders against stress and bad emotional state in general.
Especially as you get older, a dog reduces (according to studies) work-related stress by 40%, improves your concentration and productivity, and keeps depression and anxiety at bay.
That’s pretty much what a Tudy can do in a human home. All it takes is for the person to also be inspired and welcome it in.
