My 2 favorites are these:
Many years ago when an adored dog died, a great friend, a bishop, said to me, "You must always remember that, as far as the Bible is concerned, God only threw the humans out of Paradise."
"There is only one smartest dog in the world, and every boy has it."....I got to be that boy the last 12 and a half years with Kita
and I'd have to throw this one in too...."To err is human—to forgive, canine."
