Furniture Chewing
When pups are teething, they like to chew on objects, but when they are not puppies anymore, chewing on things could mean something else. However, this does not necessarily mean that they are bad dogs. Chances are they are not getting enough physical activity. A good way to deal with this behavior is to take the dog out for a walk. Give them exercise if you notice your dog is starting to chew on the furniture.
Frequent Barking
Dogs bark for several reasons. If it is frequent, the reason might be urgent. Maybe they sense danger and are telling you about it. They continue to bark as they are eager and alert- they are hearing something alarming and need someone to notice it. However, it is also a sign to alert others they are there and beware.
