Are Sealyham Terriers good with other dogs?

Sealyham Terriers can be good with other dogs, but it often depends on their early socialization, training, and individual temperament. Like most terriers, Sealyhams have a bit of a feisty streak and can be prone to assertive behavior or showing dominance, especially around other dogs of the same sex. Early and consistent socialization with other dogs is key to helping Sealyhams develop positive interactions. Introducing them to a variety of dogs from a young age can reduce territorial or aggressive tendencies.
