Are Cairn Terriers good for first-time pet parents?

No, Cairn Terriers are not the best choice for first-time pet parents due to their high energy levels, independent nature, and strong-willed personalities. They require abundant training, mental stimulation, exercise, and attention to help them thrive and prevent behavior problems. 

That said, Cairn Terriers are rewarding and loving companions with the right care, training, and commitment. If you are a first-time pet parent considering a Cairn Terrier, do a lot of research, talk to breed experts, and be prepared to provide the time, effort, and resources needed to care for and train your new pet.
