We know tools can grant advantage on ability checks when situationally appropriate. I have no issues with tools being alive / living things counting as tools. So I can parse the mechanic as "The guard uses her [Trained Dog] tool to gain advantage during watch tonight."
I also know how intelligent a well trained dog can be, but my answer might be different with other animals. Training a first generation tyrannosaurus is probably a whole different kettle of fish with totally different instincts and capacity to be trained. Ultimately, it depends on how the player presents the scenario to me. I might allow them to Work Together, or I might ask them to roll separately. Whatever I decide, I try to be as consistent as possible so my players can make informed decisions in the future.
