Lost our little buddy

Our little man was 14 1/2 years old First small dog we ever had by far the best He never left my wife’s side He was never carried he walked everywhere he never liked to be picked up my wife is so down I am too, but she is not handling it very well we have another one that is seven
When is an appropriate time to get another one. I think that my other one is getting sick from being alone. She won’t eat.View attachment 1715842611
Sorry for your loss. We lost our dog at 16 yr. and just lost our cat this July at 16 yr. It's HARD!
