King Charles II of England issued a decree in the 17th century allowing toy spaniels, also known as King Charles Spaniels, to be kept inside the Houses of Parliament. These small, friendly dogs were named after the king, who was known to be fond of them.

King Charles Spaniels are small, affectionate dogs with long, silky coats and a gentle, docile nature. They are known for their loyalty and devotion to their owners and make excellent companions and lap dogs. They are also intelligent and easy to train, and they are often used as therapy dogs due to their calm, gentle disposition. King Charles Spaniels are typically good with children and other pets and are generally easy to care for, making them a popular choice as a family pet.
