Yellow Labs?

[Tiger Tiger]

Hi
At an inch long i am told it's hard to tell the sex of these yellow labs, however there is a destinct difference in colour, Some are without doubt a very much fuller brighter yellow while some are much more pale looking.
Could these mean a difference?

Not really...they are impossible to sex. unless you vent them.

^ No they arent.

Sexing at that age is difficult. But the dominant male will most likely be the biggest, most yellow, and have the most flack finage. Bascially, all those show dominance. Other than that, there isnt any other way of sexing them that im aware of.
