Long post for details.
My partner and I are currently on a sit with 2 GSDs for a few months. It’s been a couple of weeks. At first everything seemed fine. The owners are retirees and just go on drives most of the time and play fetch occasionnally. We think they mostly potter arond the property and the dogs were content with that. They don’t seem to get other stimuli.
My partner and I work from home and can play fetch when the dogs need interactions and activity.
Now our problem is with tennis balls while we’re not playing fetch:
Dog 1: is pretty passive. She seems to not want to run after the ball but after the other dog, snarl at her and try to get her while running a bit after the ball. She seems to really enjoy this and wait to throw the ball to do this again. She’s not aggressive toward the other dog at all. Here’s where it gets tricky… if she gets the ball, she won’t drop it. Doesn’t want you to take the ball and will walk away if you approach. But she’ll still “play” fetch and continue to chase the other dog. She gets really excited about this.
Now Dog 2: seems to enjoy balls a lot. She’ll just chew on them most of the day and carry them around a lot of the time. She loves to play fetch and really runs after the ball, brings it back and drops it so we can throw it again. A good fetch dog.
However, when we’ve finished playing is where the problem has started recently:
When we arrived here a few weeks ago, when we were done playing, dog 1 will just hold onto her ball, and dog 2 will also hold onto the ball, both come inside, chew and they’re both happy and eventually lose interest.
A few days ago, dog 2 would get aggressive with dog 1 when she had a ball and they didn’t , she’ll bite at the scruff until dog 1 lets go. It only lasts a second or so but it seems so violent. Even if there were other balls in the house but dog 2 just didn’t see them or forgot about them.
And now, twice today, dog 2 doesn’t even want dog 1 to have a ball once they’re done playing. She’ll get very aggressive and make dog 1 drop it even if she already has one herself! She grabbed dog 1 by the scruff and wouldn’t let go. This lasted easily more than 5 seconds, which is a long time to fight over a ball that was already dropped.
We tried confiscating the balls so no one had them, dog 2 just got aggressive with dog 1 for no reason, though it was just before breakfast so maybe they were just hungry (?).
We don’t have experience dealing with resource guarding dogs and we’re afraid the issue could get much worse in the 2 months left we have.
The HO never mentioned this could be at all an issue.
Is dog 1 the problem? She doesn’t want to relinquish the ball at all, ever so dog 2 has had to resort to being aggressive if she wants it?
We don’t want anyone to get hurt and it’s becoming stressful. We don’t want to contact the HO yet and worry them if we can sort this out.
Does anyone have advice?
