The Old English Sheepdog is classified by The Royal Kennel Club as a large breed, typically weighing 27–45 kg as an adult. Nicknamed the "Bobtail", this shaggy, profusely coated breed was historically used for droving cattle and sheep to market, and is known today for its distinctive rolling gait and famously good-natured temperament.
What this means for your Old English Sheepdog
Hip dysplasia, progressive retinal atrophy, and hypothyroidism are all worth screening for. Deafness also occurs at a higher rate in dogs carrying certain coat-colour genes, so hearing checks are worthwhile, particularly in puppies.
The dense double coat needs regular, thorough grooming to prevent matting, which becomes an even more important routine to maintain as your dog ages and becomes less tolerant of skin irritation.
When is an Old English Sheepdog considered a senior?
Under The Royal Kennel Club's size-adjusted guidance, large breeds like the Old English Sheepdog are generally considered senior from around 5 dog years old.
