My oppinion is yes but it depends on the person and the dog.
When the female is ready the male will know.
I have a male lab and he is so playful and affectionate but females are just as loveable.
Golden retriever is cuter.
yellow lab is cuter and better
Yes
Male: 22.5"- 24.5" Female: 21.5"- 23.5"
Keep them separated.
Yes
As long as they are spayed and neutered.
when a male and a female joined they make baby.
If the female carries the recessive gene necessary for yellow coloring, about 50% of the time. If she does not, never.
if the female and male are domnant black then you wont have a chocolate labrador
