Have an 8 year old male Standard - bring in another?

Question
I apologize... the adoptee is a standard 8 MONTH old male apricot... Not 8 year old as I previously stated.

Answer
I am confused and can't find you previous question. In general, it is best to avoid 2 of the same sex, but 2 males are less likely to be a problem than 2 females.  With younger dogs, it is best if they are at least 6 months apart.

Once past 3 years old, many dogs don't want anything to do with puppies, their sharp little teeth, and their biting games.  You need to teach the puppy to leave the older dog alone.  As soon as the puppy starts to focus on the older dog, give it a sharp ''Ah, ah, ah!'' and offer it a chew toy.
