My family has a 14 yr old lhasa also-shitzu mix female who is going blind, has a history of lime disease, and has what I believe to be a few benign fatty tumors. She doesnt seem to be in any pain however and you would never guess her age by her behavior. She has had accidents her whole life but recently is peeing everywhere. She has a dog door that leads outside to a large pen with kitty litter and a tarp over it. Until recently the door had led to a path along the deck that led to the grass but she was peeing on the porch and ruining it. Since putting the cage there her accidents have become an all the time thing, whereas it used to be a maybe once or twice week thing. My family is fed up with this and are not willing to maintain a diaper for her and are thinking about putting her down. Personally I dont see how anyone could kill something that has been a part of the family for 14 years, over incontinence inconvenience. I would take her myself but my apartment does not allow dogs. Any suggestions? Willing to try anything.
