During the cold war, the Soviet Union developed the Black Russian Terrier as a working military dog. During the early 1950’s, the Red Star Kennel developed this breed and in 2004 by the American Kennel Club. The Black Russian Terrier is not really a terrier at all, but a mid-sized working dog used for hunting and guarding or as a pet. The Red Star Kennel is thought to have developed the BRT using a wide variety of breeds – as many as seventeen – including breeds like the Newfoundland, the Rottweiler, the Caucasian Shepard Dog and a Giant Shepard and an Airedale. So, you can see the wide variety and several more breeds were added. The Red Star Kennel in Moscow was owned by the state and they developed the BRT for specific working conditions and not for appearance. They did not really care how it looked except that it had to be black. In 1957 the state allowed a few puppies to be sold to non-military breeders. These breeders began to breed the Black Russian Terrier for appearance as well as function.
As these breeders worked with the dogs, they spread the breed throughout Russia and into Finland, Poland, Hungary, Germany, Czechoslovakia and Germany. From there they spread to Australia, Canada and the United States. The breed standard was developed in 1958 and by 1996 an updated version of the standard was developed to reflect the dog we see today. In 1996 the United Kingdom also got their first introduction to the breed. They are still rare outside of Russian or previous Soviet Union states.
The origin of the Cavalier King Charles Spaniel goes back many centuries. It was in 1928 that this spaniel breed was separated from the smaller King Charles and these were particularly popular with royalty in England.
In fact, Mary, Queen of Scots had one of these spaniels who accompanied her to her beheading. It was her grandsons who gave their name to the breed, and King Charles II, who reigned from 1660 to 1685 kept these dogs. After Charles II's death, the dog’s popularity waned somewhat. The dog was later bred with pugs giving them the familiar features they have today, such as the domed head and the shorter nose.
Interest in the breed revived, and a breed -club was established, drawing up a breed standard. Finally, in 1945, the Cavalier King Charles Spaniel was recognized as a separate breed.

Cavaliers are generally fairly healthy dogs but they are prone to mitral valve disease which can lead to heart failure. The heart as 4 chambers and each chamber has a one-way valve to keep blood from flowing backward. One of these is the mitral valve and it can leak over time resulting in a heart murmur. Dogs as young as 4 years of age can develop a murmur from a leaking mitral valve.
Congestive heart failure develops, your dog has a chronic cough and lacks stamina. A veterinary cardiologist may need to be called in to recommend some kind of medical intervention. The vet will evaluate your pet's condition and lifestyle before making a recommendation.
Other health problems which the Cavalier might have to contend with will be luxating patella as well as eye issues.
