Oftentimes, early socialization and training are the keys to preventing dog aggression. When your dog is young, introduce them to cats, allowing beneficial interactions to occur under supervision.
To reduce the likelihood of disputes, give your dog and cat separate living spaces. Allocate particular areas of your house for each pet to retreat to when necessary. Physical boundaries can be established by installing pet doors or baby gates.
To help your dog get desensitized to cats, gradually introduce it to supervised cat surroundings. To begin acquainting the two pets with one another's scent, start by trading toys or bedding.
When introducing your dog to a new cat or the other way around, pay close attention to how they interact. Make sure your pets are first leashed in order to keep them under control and take appropriate action. Reward calm.
See a professional dog trainer if your dog's hostility doesn't go away despite your best efforts. In order to properly manage the aggressiveness.
