I totally understand how you feel. If I had different living conditions, I would have had another dog probably in early 2005. But, my living conditions, and the way I felt about Duke, wouldn't let me. In my case, I was wanting another dog for reasons for me. For making it easier when Duke did pass. That wouldn't have been fair to him. In your case, it's different. If Nicki need more companionship that might make her happier, that would be great. I would take the dogs being considered to the house to meet Nicki, if possible, before choosing one. I wish Nicki's pain could be relieved. Like I told you, it breaks my heart to hear that she's not doing well. Please hug her until you're tired of doing so. Those would be from me.
