• Old Dog's Back Legs Giving Out: Causes and What to Do

  Back legs giving out is sudden or gradual, and the causes differ.

If the weakness came on over hours or days, call a vet now. If it crept up over months, book an exam.

• When Is a Dog Considered a Senior? Age Chart by Size

  A dog is a senior in the last 25% of its estimated lifespan (AAHA, 2019), so no single age applies. Clinics quote about 7 to 8 years, and 6 to 7 for giant breeds. If your dog is within a year or two of its range, book a senior exam. Otherwise keep annual visits.
