My sister lives with my parents who are elderly and dependent on care. They do not get around independently. She works in the early AM, comes home and helps mom up and gets her settled in her chair witha meal and tea..gets dads braces on and rebanages and diabetic wounds ect, naps, does errands with dad, does all doctors appts and does dinners and all the laundry ect. She goes to bed at 8 or 9. I come over at 1030p and do the same thing but in reverse. I do some cleaning and repair of broken things ect. Mom has survived lung cancer 5 years out has COPD and still smokes like a chain, My sister cant have kids is 45 and is extremely lonely and depressed. I am 43 have 4 kids, a husband, rent our own house. I moved back to town to help my sister 2 years ago when she seemed overwhelmed. We share the duties. She is so lonely and has always wanted a dog. My parents are adamant that she cannot have one. My mom says the doctor said that even the hypoallegenic dogs will aggrivate her COPD(i agree a fur bearing dog would but not one that grows hair and produces no dander). Her chain smoking doesnt? She will give us all lung cancer and COPD like her with her chain smoking second hand smike but not a little dog to help my sister have some joy and unconditional love in her life? My dad says they will end up taking care of it, even though i have already explained that they would never see the dog except when my sister carries the little thing outside to relieve itself, and stay in her room UPSTAIRS for the remainder of the time, and while my sister is at work for up to 5hrs only at the most the dog can be trained to stay in a crate. It would change her emotional health completely to have something of her own to love and be loved by, give her joy, something to look foward to, and personal companionship, she is sad she will never get to have children(fibroid hysterectomy at 35). My heart is so heavy for her lonliness.They are selfish? Or am I asking too much unreasonably? She is not an irresponsible person who would leave the little guy for them to care for, she knows they cant. I am sort of enraged by their lack of sensitivity. She is struggling with finding any joy in her life. I told her to get one and keep it at my house since i live right around the corner! Input please.
