To prevent dogs from being possessive over toys, use the same approach as you would for stopping resource guarding in dogs. If you have multiple dogs and some jealousy issues, a good dog training tip is to teach your dogs to leave the room, but use different cues for each dog. This way if you see one dog getting stiff or showing other signs of guarding behavior, you can tell the other dog to leave the room. Since Rex is the dog with the guarding behavior, I recommended the guardian teach Opie how to leave the room on cue and not teach it to Rex. The other dog had the item, Rex received a reward when the other dog approached the object or took it. It’s best to approach it in a positive way. When working on this lesson, remember to keep training sessions short and consistent. Practicing this with a jealous dog multiple times a week will improve the way they view other dogs sharing their toys. The guardian needs to create situations where she can control both dogs. The guardian should focus on Opie and Rex when giving treats, especially when Rex is looking at another dog. It’s important to teach the dog that when the other dog gets the object, Rex will get a treat. This is how to stop dog toy jealousy.
