We recently got a great dane, so first question is do you allow great danes to take your classes? 2nd if allowed what do you recommend if you have already taken the basic obedience course with another affiliate. 3rd our new girl is having some behavior issues. AKA she doens't like my husband. She barks and used to lunge at him. She's gotten better but still barks at him upon his entering the room. We are doing everything we can think of. Any thoughts and ideas are greatly appreciated!!!
