to introduce a new rottweiler to our rottie at home

Question
We have a rottweiler. She is 10 years old.We've taken in another rottweiler who seems very gentle.She is about 18 months old.Our older dog is aggressive toward the younger dog.What can we do to help our older dog tolerate the youger one. Thankyou .

Answer
Well the best way is to just have them sniff each other through a gated off room if you can,but if you can't do that another thing to do is when you pet one,pet the other one at the same time so that they won't get jealous,also playing with both of them in the yard together so that they can include each other in play is a good idea too
