The Irish Russian Spanterrier is a designer dog, an intentional crossbreed between the Irish Water Spaniel, a medium-sized waterfowl retrieving canine that was developed in Ireland sometime before the 1600s, and the Black Russian Terrier, a giant breed dog that began development as part of the national security force in Russia in the 1930’s. The Irish Water Spaniel is the largest of the spaniels, an energetic dog that has been around long enough to be mentioned in literature from the 1600s. The true heritage of this ancient dog breed lost to history, though many have speculated that breeds like the Poodle, the Portuguese Water Dog, the Irish Setter, and the Curly-Coated Retriever may have contributed to the breed at some point in their history. They are both wonderful family dogs and excellent versatile hunting dogs who can handle most aspects of flushing and retrieving game birds but excel at nosework and have a strong desire to locate targets. These traits made them very popular in early America and in 1875 the Irish Water Spaniel had become the 3rd most popular sporting dog in the United States and was recognized by the American Kennel Club in 1884. Although the Golden Retriever has taken its spot in the popularity rankings and the Irish Water Spaniel has dropped to 150th place in popularity, this breed still has a small but dedicated fan base. The Black Russian Terrier is a very new breed compared to the Irish Water Spaniel. Developed in military kennels outside of Moscow, this canine was designed as a native Russian breed of dog that was to be employed as a large animal that could both be highly trainable and reliable, as well as being able to think and act independently when needed. A total of seventeen different breeds were utilized in developing this immense guard dog but the four dogs who most heavily influenced the breed include the Giant Schnauzer, the Rottweiler, the Airedale, and the Newfoundland breeds. This large, confident, and independent thinking animal began to breed true in 1956 and was internationally accepted by the FCI in 1984 and but not into the AKC until 2004.
