HiSteve,
don't worry about your puppies and get the cycads you like. the leave of none of them is so toxic that would kill a dog or cat or whatever just by eating a piece of it (don't think your puppies will eat a lot more as the leaves are very coriaceous!). Furthermore, puppies are more intelligent that what most people think, if they try the leave and get a bit sick (maybe they will vomit and get soe stomach ache but not more than that), they will not get on that plant anymore - that's exactly the theory behing spraying plants with chili oil to teach cats they should not eat them...
ok, I admit cats can be a bit more silly than gods in this case, as they are looking exactly for the emetic effect when they eat the plants
