The first step to managing a possessive dog is to recognise the warning signs of possessive behaviour: Refusing to give up a toy or treat when asked, Snapping at other dogs while eating, Hoarding toys or treats, Growling at other animals while holding a toy.
The most immediate way to control your dog’s possessive behaviour is to prevent access to the things he guards.
If your dog is possessive over “high-value” items like certain chews for example, the easiest solution is to not bring those items home.
You can also use doors and baby gates in your home to keep your possessive dog separate from resources he may guard.
Sometimes, a possessive dog needs a basic obedience refresher course, All the basics, from “sit” to “stay,” are important for your dog, but these three commands are most useful for dogs who tend to hang on to resources: “Leave it!”
This command tells your dog to ignore a compelling treat or toy and focus their attention on you, or to walk past an enticing morsel on the street.
“Drop it!” A key command for all dogs, “drop it” is especially helpful for dogs who get possessive about toys.
Training your dog to reliably “drop it” can help prevent possessive behaviour before it starts.
“Swap” or “Trade” is a cousin of “drop it,” and is useful if your dog won’t drop the item she’s guarding.
Essentially, you offer a “better” resource than the one they’re guarding.
Use “drop it” when your dog refuses to let go of a tennis ball, and show him a particularly tasty treat, say “trade,” and follow it with a “sit.”
When he sits, he gets the tasty treat as a reward, and drops the ball.
NILIF training is a positive, safe way to remind your dog that you control the resources, and it can greatly reduce possessive behaviour.
Desensitisation and counter-conditioning training is a gradual, deliberate process of changing your dog’s behaviour, it’s useful for dogs who guard their food bowl, or growl when you try to take away a toy.
Desensitisation and counter-conditioning training is very effective, but takes a lot of time, patience, and consistency.
