Well like people they can come in a variety of personalities but the most common are playful youths turned calm adults. Mild tempered and very easy to handle. Have never experienced a truly aggressive dane. Training is very easy for them especially in pack mindsets. Have them take the mothers lead or a leader figure animals lead on potty/training habits and they take very quickly. Sexually they are a very large breed when it comes to their sexual organs. Build trust and love with them and they are VERY receptive. Males are easy to initiate but females require a wait for their first or second heat. Recommend second due to them being so new to the experiences in their first. Introduce the idea of being around them and their organ during the first then work your way towards penetration with the second.
