I appreciate the continued comments and suggestions , we are not looking forward to the rainbow bridge crossing

Right now our male that is 16 years old is showing signs of dementia and having trouble controlling bowels . The 16 year old female is somewhat blind but otherwise pretty healthy . The 13 year old male with the partial paralysis is generally healthy but he too because of the paralysis is having more indoor accidents than we would like . My wife and I love these weiner dogs and will wait as long as we can before heading to the vet .
I have been a dog owner/lover since I was a young child so this is not the first time in this situation and it is never easy to decide when the time is right . But I am a true believer in not letting them suffer . So far I don't think they are . My wife and I have also discussed the possibility of going " dog free " for maybe a year to do some things we haven't been able to do with 3 dogs . I have a feeling 2019 is going to be a painful dog year for us
