 Toy spaniels continued to be popular in the British court during the reign of King James II , through that of Queen Anne . Popular types included those of the white and red variety . Following the Glorious Revolution in 1688 and the reign of King William III and Queen Mary II , the Pug was introduced into Britain which would eventually lead to drastic physical changes to the King Charles Spaniel . Comparisons between needlework pictures of English toy spaniels and the continental variety show that changes had already begun to take place in the English types by 1736 , with a shorter nose being featured and the breed overall moving away from the one seen in earlier works by Anthony van Dyck during the 17th century .
