Hi anna!

Not to make it anymore confusing, but also take into consideration that neutering may not totally alleviate the issue.

I had Gully neutered before 7 mos and he showed some aggression after being neutered. He really loves his food and does not like Oz and Murph coming near it. He seems to fully trust me, so I've had no issue. I've even been able to take a cooked pork bone directly from his mouth, but other dogs is a different story. Oz is not too big of an issue, because Oz doesn't challenge him, if Gully gives out some signals to back off. Murph, however, due to being old and a terrier, is a different story. He doesn't see and hear as good as he use to, so I don't think he picks up on Gully's body language. And he'll just march himself up to Gully's bowl and push Gull out of it. Then when Gull tells him to back off, he won't. So far it's all been posturing, some growling and air snapping between them, no actual fighting.

Murph being so small and fragile now, I worry about Gull hurting him without even trying though. Can't magically resolve the issue by neutering, because they're all neutered. So I keep up with making sure none of them get anything for free. Everybody must Sit or Down for treats or dinner. And once they do I give Gully his first. That seems to have helped tons. Also, when Gully's eating, I keep Murph away from him, even to the point that if Murph finishes his treat first, I pick Murph up off the ground, until Gull is finished with his. Me being more aware and keeping consistent with training has been key.
