Thanks Gwen,

I wasn't aware of the Sago Toxicity but I'm glad to know now. I have 5 in the front yard and haven't had any problems with the dogs trying to eat them. I've had them for 9 years now and other than the male dogs using them as a object to lift their leg on I've had no problems. The branches are very prickly so maybe that's why. It's good to know though and I will pay more attention to the dogs chewing on them.
