I have a four-year-old ragdoll cat and a one-year-old miniature schnauzer puppy (about half the cat's size). The cat has learned to tolerate the dog and only retreats to high ground if she is actively being pestered. Neither animal has even been aggressive toward the other.
I recently took the cat outside to explore the backyard and enjoy the warm weather. This trip happened to be her first time in the yard since getting the dog. When she returned inside, she was immediately very skittish around the dog, seeking a hiding spot if she even heard the dog in another room.
The backyard is where the dog habitually releases waste, so I'm sure it must smell very much like her to other animals. Did I inadvertently create a dominance issue by introducing the cat into the dog's "territory"? If so, is there anything I can do to reset the scales? It's been a couple days since this started, and the cat is showing great improvement on her own, but I wonder if there's anything else I can do to help besides wait.
