Dead men hear no tales; posthumous fame is an Irish bull.

Distant hills look green.

Don't bare your teeth until you can bite.

Don't bless the fish till it gets to the land

Don't build the sty until the litter comes

Don't bother with the beggars son and he won't bother with you.

Don't count your chickens before they are hatched.

Do not mistake a goat's beard for a fine stallion's tail.

Don't rest your eyes beyond what is your own

Don't interfere with [any] thing that doesn't concern you.

Don't tell your complaint to one who has no pity

Don't throw out the dirty water until you have the clean water in

Drunkenness hides no secret[s].
