I would say the golden retriever is the oldest. Because the oldest one of the golden retriever breeds was a twenty two year old. which is one hundred and fifty four in human age!
Usually by age 1.
the oldest lab age would be 15 but normally its 13
A female Labrador can go into heat as earlier as 6 months of age. However, usually it is around the 8 month range.
It depends on the personality or health I'm sure...
the oldest one was 19.5 years old!!
That all depends on the age, size and temperament of either dog. Typically, a dog with a more nervous energy is one that is more prone to losing than one that is more dominant, because in the dog world, such energy is weak energy, no matter what size or age either dog is.
The average age for any dog to be altered is 6 months--but can be done when the balls drop.
The life span of a Basset Hound is 8 - 12 years.
Labradors are a playful, slow maturing breed, that do not reach adulthood until at least 2yrs of age. Do Not breed them before then.
when it gets to the age of 1 or weighs the same as an adult dog
some reach age 17 but most 9-14
