I think shes doing it as a result of being tied out. She's 12 and just about her entire life she has been let out to run around and do her stuff. Recently we have had an issue with a neighbor and as a result, we now have to tie the dogs out. She's also getting old, losing her eyesight etc. Unfortunately, its really the only option we have for her at this point. But honestly, if the worst she and I have to deal with is pooping in the driveway, I really dont mind. I have had her for 10.5 of her 12 years and that dog has been worth her weight in gold a thousand times over. From protecting myself and my children from a peeping tom to helping to teach babies to walk, she has done so much for our family and will be with us as long as possible!
