I was reading the “fleet hint” and thought I’d add that you can buy aquarium tubing from Wal-Mart, or a pet store.  The aquarium tubing will fit on a syringe end to make a nice drench.  I have used it for a cria needing Dyne and he took the tube well. I could easily cut it to a size he could manage.  Take the syringe with you shopping to make sure you get the right size for its end.
