Chapter 5: Size, lifespan, and space at home

Large breeds like Labradors need room to stretch and cool floors to lie on, which matters in our heat. Small breeds suit condos and apartments but may struggle with stairs and narrow corridors. Consider how long the dog will live, as larger breeds often age faster and may need more vet visits later in life. Match the dog's adult size to your actual living space, including whether you have lift access and a safe area for daily exercise.
