How can I successfully introduce and integrate a dog and cat to live together harmoniously?

Introducing a dog and cat to live together harmoniously involves gradual introductions, positive reinforcement, and providing separate spaces for each pet. Start by keeping them in separate rooms and gradually allow supervised interactions. Use treats and praise to reward calm behavior. Provide separate feeding areas and litter boxes to prevent resource guarding. With patience and consistency, your dog and cat can learn to coexist peacefully.
