I had a 13 year old labxgsd and a 2year old labxclliexgsd when we got our pup, well when we bought him home we introduced him to the eldest first and they all got on brilliantly, we had a crate for the pup to go in already set up and used to put the pup in when things got a little too much for him and he needed to rest.(he wouldnt go to sleep in case he missed something!!). Our old boy sadly had to be put to sleep a month after we got the pup as he developed liver failure so we didn't really get to find out how their relationship would develope but the other 2 are brilliant together and play endlessly!!
I am sure Goeorge will love his new addition and as long as they are introduced well and you remember to buy 2 of everything!!

then i am sure your household will be as happy as ours!! Oh and BTW remember to leave them to sort out their own ppecking order this is something that doesn't just come with age, our 5month male is dominant over our 2 + 1/2 year old!! so don't just assume that because George is the oldest he should be the boss as dog life just isn't like that!!
