I own two males. The oldest is 1 1/2 years...he does not mark...meaning tinkle a little over everywhere. Reese was neutered at 6 months. He has just started cocking his leg. I have no issues with him going inside my house.
Reggie, my baby at 5 1/2 months...is a marker. He will potty a little everywhere outside. He hasn't been neutered yet.
I have a female...she marks.
I see no difference in difficulty potty training.
I love my Ramsey girl...but after owning males and a female my preference is male.
When I was searching for a biewer to add to Ramsey and Reese...I was only interested in a male.
