  • The first year of a beagle’s life is considered the puppy stage, equivalent to about 10.5 human years. During this puppy year, there is very rapid growth, teething begins, and excitable puppy behavior is displayed even as they begin learning and being house trained.
  • By two years old, a beagle is fully grown in size and reaches adulthood physiologically. The equivalent human age is around 21 years. At this adolescent stage, house training should be well established and the puppy energy starts transitioning into a more mature adult beagle.
  • From 3-7 years old, ages 25-41 in “human years”, beagles are in their prime mature adult stage. They have typically calmed down energy-wise, health is at its peak, and this is considered the best stage for training and getting active with a beagle companion. Their whole demeanor exhibits adult maturity compared to the previous puppy stages.
  • At age 8 or 9, around 45-49 human years, beagles start moving into their senior years. Early age-related changes slowly begin being noticeable. Possible signs are slight graying fur, needing a bit more rest, or the beginning of weight gain issues if overfed. Routine veterinary care becomes very beneficial at this life transition point.
  • From 10-15 years old in beagle age, or 53-73 in terms of “human age”, a beagle is considered a senior. Health issues will require more attention as the aches/pains of aging increase, senses like hearing/vision slowly decline, and more sleeping/rest is needed. Providing comfortable beds, proper medication, and adequate stimulation/exercise helps maintain a good quality of senior life for beagles in their later years.
