Help: In situ oligo probe design

I'm about to start some non-radioactive (digoxigenin-labelled) in situ 
hybridisations on mouse embryos.  Is there any dogma on probe size using 
oligodeoxynucleotides?  There's a 37-bp sequence conserved between mouse 
human and rabbit that looks suitable for the probe - should I get the full
37-mer synthesized, or would a smaller probe be just as effective?  Also,
is secondary structure a consideration?  (The putative probe sequence can
potentially form a hairpin loop with 6 complementary base pairs and a
5-base loop). 

Thanks in advance for any help,
