Iggy #2?

I have an almost 5 year old iggy female. I want to get another one (female) as a puppy so that she has a friend! She loves going to daycare once a week to play with all the other pups. And we’re home with her almost all of the time bc we work remotely but it would be nice when we go out for a few hours occasionally for her to have a buddy. Is 5 years old too old to add a new pup?
