I was told between 5-6 months for spay. We did Kasha at exactly 6 and it worked out nicely because she had 8 "shark teeth" (both baby & adult) which needed to be pulled. Had I gotten it done earlier I most likely would have had to put her back under. Also, she went from about 3.5 lbs to 5.2 in those 2 months.
I don't think it's very common for small dogs to get their heat before 6 months I only know that both my Scotties were well over 10 months when they got theirs.
