Has anyone benefitted from them? I get lonely and want a dog. Likely a smaller one because the size of my house. The only reason why I haven't persued it that much is because I'm worried he or she will be to hard to manage with exercise and walks(another reason why small is preferred) and picking up waste. Most studies seem to say dogs can be really beneficial to health and people with chronic illness. They extend the life of elderly. Not to mention the fact that they can detect certain biological changes in the body before you realise. I've only heard of them detecting sugar spikes and cancer but I'm sure they can detect other changes too. Anyone had experience with pets?
