Borzoi: The Sighthound With ALS-Linked Gene Research

Worth knowing regardless of whether you're buying a puppy: degenerative myelopathy, a hereditary spinal cord condition documented in Borzoi, has been traced to a specific genetic cause — a SOD1 gene mutation. That's genuinely notable because it's the same gene associated with ALS in humans. A DNA test exists to screen for it, and it's worth asking a breeder about directly. This isn't just a health footnote; it's one of the more scientifically interesting cross-species genetic findings in purebred dog health.

As sighthounds, Borzoi hunt by sight rather than scent, and their field of vision reflects it: roughly 270 degrees, compared to a human's 180. Combined with genuine speed, this explains both their historical effectiveness hunting wolves across open Russian terrain and their very strong modern-day instinct to chase anything that moves.

Worth knowing before relying on one: a Borzoi's chase instinct is strong enough to override the deterrent of an underground electronic fence entirely. If a Borzoi sees something worth chasing, the shock won't reliably stop them. A physical, securely fenced yard is a real requirement, not a preference.

Hill's Pet offers a refreshingly direct characterization worth passing along: Borzoi are adequate watchdogs — they'll bark — but that's about the extent of their protective ability; they're not actually good at defending you if it came to it. Training sessions are typically met with a sense of humor rather than eager compliance — a Borzoi will do a "semblance" of what you ask, especially if you make it genuinely fun, but always seems to frame it as a favor rather than obedience. They're sensitive, deeply bonded to their one family, and friendly-but-not-gregarious with strangers.

Given both their hunting instinct and considerable size, Borzoi should never be left unsupervised with small children. The same instinct applies to small pets — cats or other small animals in the household need careful, early socialization, and even then, outdoor situations where a cat might be seen as fair game are a different risk than supervised indoor coexistence.

Worth knowing: "Borzoi" is actually a generic Russian word for sighthound broadly, not just the name of this one specific breed. Russia has several regional sighthound types — the Chortai, Tasy, and Taigan among them — that fall under the same general term. The breed westerners specifically know as "Borzoi" was called the Russian Wolfhound until 1936.

Beyond degenerative myelopathy, bloat is the most commonly cited health concern, a genuine emergency in this large, deep-chested breed. Borzoi reach full height by 18 months to 2 years but continue filling out in muscle and body structure until 3 to 4 years old. Lifespan is commonly cited at 9–14 years.
