When is it a senior?
The AVMA says a dog is a senior in the last quarter of its expected life: for this breed’s weight, from 8–10 years old. From then on, a vet checkup at least twice a year.
How much should it eat?

How old is it in human years?
By the formula from a 2020 DNA study: at 1 year it’s like a 31-year-old person, at 3 like a 49-year-old, at 7 like 62, at 12 like 71. The formula was found in Labradors: for other breeds it’s an estimate.
