I know I said he looked husky in the markings (I was thinking that instead of aussie) but I wasn't meaning he didn't look Corgi, he definitely looks mostly like a corgi to me in the second pic, and completely adorable of course. I think the first pic makes him look like a bigger dog, he looks smaller in the second pic. He reminds me of Dappledoxie's Tucker (Brandy if you want me to remove this link just let me know I hope you don't mind)

Have you had dogs visit your house to play with Gonzo before? If he's been fine with that I think he would be ok, but neutral grounds is probably best.
