For me it would be equines, but I have been in love with horses all my life. I like dogs as well, but the equine form is just far more pleasing to me. Also, I have yet to ever form the same depth of bond with a dog than I have with a horse. I'm not saying it's not doable, I'm just saying that I haven't. And for any of you naysayers out there, yes, I have owned many dogs throughout my life, and currently own two now. As much as I love and enjoy my dogs, the connection I have with my horses is just so much deeper and stronger.
