Hi, there!
I've also been experiencing resource guarding issues with our 2-year-old female greyhound, who we adopted 5 months ago. First of all, she is extremely curious and bold. She meanders through the areas of our house that are accessible to her and looks for things to steal. We've already limited her access to the main floor where we keep things out of reach and keep an eye on her when we're home. But even so, she manages to find things to take - mail, books, socks, towels, aluminum foil off the counter tops- and when we try to take them away, she growls and snaps and threatens to bite.
The other problem is that she will actually eat these things. For example, I took her to a playdate with some other greyhounds and she found a tissue to steal and ate the entire thing before I could react. Because of her guarding, I didn't want the other owner to try to take the tissue out of her mouth because she gets aggressive quickly. Instead, I chased her around the whole night, trading her treats so she would give up toys and other items she wanted to tear apart and devour. We've had to ban plush toys in our home because she can saw off pieces in seconds and will gulp them down.
She will give things up for treats, but sometimes it takes a lot of treats to get her to give something up on her own. We've been told by other greyhound owners that her behavior is not typical for the breed and that she is one of the most naughty/bold greys they've ever seen.
There are lots of things she's great at - doesn't have any issues being pet or touched, doesn't statue anymore on walks, doesn't bark or have any aggression toward other dogs, isn't aggressive toward other people.
She's been to the vet twice, once for her spray and blood work and another time for a thorough checkup from our regular vet. We told them about her behavior and they seemed more less concerned about the aggression/eating and more impressed that she doesn't seem to suffer any digestive distress as a result of her behavior.
We signed her up for dog obedience courses starting next week to try to learn how to correct this reaction, but would love any suggestions if other adopters have experienced similar behavior and corrected it in their pups.
Thanks,
Lauren
Also, she is very cute. This is her with her corgi friend.
