There are a few signs that you can look for to tell if your dog is guarding you. One of the most obvious signs is if they start growling or barking at someone who comes near you. Another sign is if they start putting themselves between you and the person or animal they perceive as a threat. If your dog starts Hackles may also rise and their tail may be held high and stiff. They may also show their teeth or lunge at the person or animal. While these are all potential signs that your dog is feeling protective of you, it's important to remember that not all dogs will show all of these behaviors. Some may only show one or two, while others may not show any outward signs at all but still be feeling very protective of their human family member.
