Hi Erica, There was recently a thread about Greyhounds & Toddlers - you'll probably see a lot of advice there that you'll find helpful. I can share my own experiences, as the mother of a 3 year old. My son is a typical rambunctious little boy, always into something, usually running & jumping at high speed, and frequently testing his limits. That includes what he can and can't do with and to the dog. A vigilant eye is key - never, ever leave them alone together, for both of their safety. I found a crate helpful in the beginning, as it has a more clearly defined boundary (I didn't shut the door - Bootsy had free rein to enter/leave). Good doggie manners are a great thing to teach a little person: I teach my son to always ask before petting any dog, to let the dog sniff his open palm before petting it, to never poke, hit, or pull.
For the most part, it's fine, it's easy. It just requires 100% supervision, but really any 2 year old requires 100% supervision, whether there is a dog in the room or not.
