Rex is an amazingly well behaved dog 99% of the time, but he has started to show signs of jealousy when dogs his guardian is fostering show interest in any of the available dog toys. The last time it happened, a dog fight over toys broke out. No one wants a dog to act aggressive when another dog has one of its toys. I’ve seen many clients whose dogs get possessive or jealous over toys when another dog wants to play with them. Many people confuse this with resource guarding. Although they share some similarities, they are different behavior problems. Jealousy in dogs can stem from various causes. Dogs might also exhibit jealousy due to territorial instincts, viewing new individuals as intruders. Additionally, inadequate socialization during puppyhood can result in fear and jealousy as dogs struggle to navigate unfamiliar situations.

Jealousy refers to the thoughts or feelings of insecurity, fear, and concern over threats to position, privilege, or relationship.
Behavior scientists have named many types of aggression in dogs, and some definitions conflate “possession aggression” with jealousy.
With our dogs, jealousy usually relates to competition over access to our attention or proximity to us, or our interactions with someone else.
Behaviors you might see that suggest your dog is feeling jealous include:
Tense body language, growling, snapping and/or showing other aggressive “stay away!” behaviors (sometimes quite intensely) when someone approaches.
Do not punish his guarding behaviors, as that will make him more likely to work hard to keep the attention competitors away.
Take it slow and be generous with treats and attention as you work to convince your dog it’s a good thing to have others around you.

Is that jealousy. I think the label is a hard fit for dogs. Most dog fights start over food or food-relate objects. Resource guarding can spread. A dog might aggress toward a housemate dog over a prized sleeping spot, a crate, or a sofa. One’s dog might guard a caregiver and not let another dog approach. After two dogs have fought a few times, there is a chance they will become so agitated that they fight on sight. The history becomes thick with anger and pain. They simply don’t like each other. A dog who is physically relaxed is less likely to behave aggressively.

Jealous behavior in pets can be an issue. Aggression can often be in the form of biting or nibbling of the animal or person getting attention over them. Growling, hissing, or getting into a fight with another pet may especially be an issue in a multi-pet household where pets are competing for attention and resources. Pets may aggressively bark, hiss, or growl when owners are greeted or visitors arrive. When you arrive home, make sure you don’t give one pet more attention than the other, or wait a bit to give attention, as the level of emotional excitement will diminish, preventing signs of aggression from occurring.

If not treated properly, jealousy in dogs can quickly escalate into aggressive behavior. A jealous dog is terrified of losing your love and attention. Your dog will try to go in between you and the other person or dog and will strive to get your attention always. Controlling aggression Territorial behavior in dogs is common, but it becomes abnormal when it becomes aggressive. This behavior is treated by rewarding and praising calm conduct, obedience training, removing triggers, making certain changes, and making it difficult for him to behave in a particular way. Dogs are more prone to jealousy than you would think. When a dog does anything out of the ordinary to get your attention, such as doing tricks, leaving the room unexpectedly, frightening strangers, going to the toilet indoors or clinging to you, you know it's jealous.

Aggression is one of the behaviors you should watch out for. Any kind of nibbling or biting to get attention over another object or thing is a bad sign. A dog's “jealous” behaviors may include snapping, getting between owner and other objects, behavior towards an object or thing you’re interacting with, and extra attention to you. Possessive behavior can be very problematic or very little cause for concern, depending on your dog's actions. If your dog is growling and biting at you as you approach them, that’s more serious. Your dog may be showing possessive behavior if they do the following: growling, snapping, whining, attacking another pet or person. A possessive or jealous dog doesn’t typically back down, they’ll continue the problematic behavior the entire time they’re in an uncomfortable situation.
