Scottish Deerhound

Typically 8 to 11 years — a short lifespan even by giant-breed standards, driven heavily by the breed's high rate of osteosarcoma and its predisposition to dilated cardiomyopathy. There is no way to fully engineer this away, but you improve the odds by sourcing from lines with documented cardiac screening and longevity, keeping the dog lean to reduce joint and cancer stress, and committing to early veterinary workup of any persistent limp or exercise intolerance. Prospective owners should accept the short lifespan as part of the decision, not a surprise.

Temperamentally yes — they are gentle, patient, polite, and remarkably tolerant. The real caution is mechanical, not behavioral: a 100-pound dog with a sweeping tail and a sighthound's sudden burst of speed can easily knock down a toddler unintentionally. Supervise interactions with very young children, give the dog an undisturbed resting space, and teach children not to climb on or startle a sleeping Deerhound. The breed is too friendly to be protective, so it is a companion, not a guardian.

Despite being a famously calm couch dog indoors, an adult Deerhound needs 45-60+ minutes of daily exercise including regular opportunities to gallop at full stretch in a securely fenced space, plus leashed walks. It is built to sprint and loses condition without it. Critically, puppies must NOT be over-exercised or allowed to jump and do stairs heavily during their long growth period — protecting developing giant-breed joints for roughly the first 18 months is as important as exercising the adult.

Only inside a fully enclosed, secure area. This is a coursing sighthound built to chase fast-moving prey, and once it locks onto a running animal it reaches around 30 mph and recall effectively disappears — this is hardwired, not a training gap. Walk on leash by default everywhere unfenced, use a securely fenced field or lure-coursing setting for sprinting, and never rely on voice control near roads, livestock, or wildlife.

Low. The harsh, crisp coat needs only a 10-minute brush about once a week plus occasional hand-tidying of straggly hairs; it is a modest shedder and not high-maintenance. The more important physical-care tasks are providing a large orthopedic bed (lean giants develop pressure calluses and sores on hard floors), keeping nails trimmed every 2-3 weeks, and brushing teeth several times weekly. Coat care is minor; joint, weight, and bloat management are where the real attention goes.

Osteosarcoma — bone cancer — is the breed's defining and most heartbreaking risk, affecting well over 15% of Deerhounds, usually around 7-8 years of age, and often presenting first as a limp or limb swelling. Dilated cardiomyopathy is the second major concern. There is no preventive screen that eliminates osteosarcoma, so the responsible approach is sourcing from health-tracking lines, getting any persistent lameness imaged early, and being financially and emotionally prepared for the possibility — it is the single most important factor to understand before choosing this breed.
