Labs are prone to hip and elbow dysplasia, so look for breeders who provide OFA or PennHIP clearances. Exercise-induced collapse (EIC), an inherited neuromuscular condition causing hind-limb weakness after intense activity, also appears in the breed — a DNA test can identify carriers. Obesity is extremely common in Labs specifically because of how food-motivated they are, and it compounds joint problems.
Labs will eat almost anything offered to them, which makes portion control essential rather than optional — measure meals rather than free-feeding, and be sparing with treats. A large-breed puppy formula through the growth period helps manage joint development.
The short, dense, water-resistant double coat sheds heavily, especially during seasonal blowouts, and benefits from brushing several times a week; the coat otherwise needs little else beyond occasional baths.
Highly trainable and eager to please, Labs excel in obedience and retrieving work, but their high energy — especially before age three — means real daily exercise is non-negotiable, or that energy turns into chewing and destructive behavior.
The Labrador Retriever traces back to the St. John's Water Dog of Newfoundland, Canada, small hardy retrievers that helped fishermen haul nets and lines in icy Atlantic waters in the 1700s. English nobles imported the dogs in the early 1800s and refined the breed into the modern Lab; the AKC recognized the breed in 1917, and it went on to hold the No. 1 most-popular-breed spot for 31 consecutive years before being overtaken in 2022.
The breed standard describes a kindly, outgoing, tractable temperament — eager to please and non-aggressive toward people or other animals — which is exactly why Labs dominate guide-dog, detection, and service-dog programs as much as they dominate family homes.
