We adopted Tia when Chile was about 1 year old. On the way home from the breeders, Chile just kept growling at Tia....the whole way! When we got home and I put them both outside, Chile just sniffed Tia for a bit and then they played together. I always gave them both EQUAL attention, because if you don't the dog that you had first will be upset....and I always gave Chile her treat first and Tia second because Chile was my first....I don't have a problem with them at all....they are the best of friends and do everything together.

I don't think that you will have a problem with your older chi adjusting to the new one.
