We have accepted ownership of our 2nd Great Dane. He is a 2 yr old male
and is great companionship to our 4 yr old female. She does get quite
bitchy at times but is generally accepting. He is doing some "marking"
around the house, mostly things that are close to or on the floor, like
a gym bag etc. Will this subside when he gets more sure that this is a
permanent home? What is the best method to convince him not to pee in
the house?

Thanx
Mike
