I really don't think you'll have a problem
Are these dogs being introduced to each other on neutral ground?
Where both of them have not been before? or is one coming into another's territory?
There you MAY have a temporary problem
They will of course need to sort out who is going to be top dog
and they will do that on their own
don't force them together ... don't force them to play
watch them eating when they are together ... because that's where signs of aggrssion will occur
