Borders are good-natured and friendly dogs. They are affectionate, intelligent and sociable. Training is easy because they are obedient and quick learners that they can easily pick up cues on things their owners like or don't like. They are highly-active dogs that need to be kept busy to be truly happy. Their instinct to chase down prey remains strong, which makes them love the outdoors more.
On the flip side, Border Terriers are also stubborn and can even quickly pick up bad habits if not properly trained. Sometimes their strong hunting instinct will overpower any command, and they will just go and follow where it tells them. Knowing this, it is crucial that homes, where Borders will live, have secure fenced-yard or back garden or else they will take any opportunity to escape.
Border Terriers also often suffer from separation anxiety and hate being left alone for any length of time. Excessive barking is their way of showing their displeasure or catching your attention. However, they can be trained to only bark when it's necessary provided that training starts at a young age.
Borders are great with kids but can be a bit hyperactive for smaller children. As with any other dog breeds, it is vital for playtime to be supervised to avoid any accidents or unintentional injuries. Border Terriers tend to get along well with other dogs and cats, but not with smaller pets such as mice, squirrels, hamsters, and birds. Their prey drive is high that they'll likely end up chasing or killing small animals.
