- They generally need a lot of exercise and walks.
- They tend to be more laid-back than smaller dogs.
- If you are choosing a dog with small children in mind, some breeds are friendlier with children than others.
- They need good training and a leader to manage them. Professional training may be best.
- They don’t handle loneliness well, so leaving them in a house or property for long periods of time is not the best option.
- Without training, they can become aggressive.
