He is a looker. I know I'm being the bad guy (gal) here but I would be REALLY cautious about letting him off leash untill his recall is MUCH better. One he is not altered and males can smell a female 3miles away & no way are you going to will against the scent of a female in heat. Two this new world is nothing he is use to and as he showed you it's more interesting than you. Not saying he can never be off leash at the beach but I just think doing it so soon is a recipe for disaster (just my honest opinion). He does sound like he is getting the handle of home life. I foster greys right off the track. It can be frustrating to get them to "get it" but it is so wonderful when they do and when they enjoy the new things.
