The Pugalier, unlike most "designer mixes" of dogs that have come into fashion only recently, may have already been present in 17th century England.
The Cavalier King Charles Spaniel, the smallest of the Spaniel family, had been the favorite of the English courts since the 16th century. As the Pug became popular all over Europe, cross-breeding might have occurred, and accounts of Cavaliers with shortened muzzles, wrinkled foreheads and large, round eyes were documented.
No matter the accuracy of the accounts, the Pugalier to this day remains a wonderful mix of two gentle, intelligent and affectionate breeds that, with the proper care and socialization, is a welcome addition to any household.
