I believe that it has more to do with their recent memories...if they have grown up around their pack, parents, siblings, they will be very open and happy ... but, and this is very important, what Gene says is so true!
We have brought puppies back after a time with new families and it is like bringing a strange dog in. The dogs don't fight, but they don't immediately recognize each other either.
We did meet with some of our adult pups in a dog park and I believe that they did remember after a time...but it took sniffing and playing before they started to bond.
So, don't expect a happy reunion...and even prepare for some aggression...it can happen.
These are doodles, afterall...and they are friendly and generally tolerant of other doodles...but intact dogs are a bit more set in their pack routine and it takes a little time for the new dog to fit in.
I would suggest introducing him slowly...to one dog at a time...
We had the mother to our pups visit when the pups were about 5-6 months old (and physically full grown) and the girl pup knew immediately it was her mother...all went great until the pup started sniffing the nipples! LOL Mama let her know right away these were off limits! The boy pup didn't recognize his mother at all...he barked and barked at her. It took him forever to warm up to her...but when he did, he would not leave her side. They played together every minute for the week that his mama was visiting.
So, it will probably be a wonderful time, but do be aware that it could take a little time and understanding...and butt sniffing!
