Moving soon, thoughts on second dog? (JRT currently)

Ok, so to begin with the layout of the current property is .10 an acre with a back yard which the JRT has full run of.

The next property will be 2 acres and I plan to fence it in approximately 1.3 of those acres.

My JRT is 2 years old and is NOT neutered. I wasn't sure if I would stud him or not but the current outlook is that he will not stud.

My dog is what I believe to be passive which is odd for a JRT but I'll explain why.

I am the ruler, the pack leader and he registers that with me as early as a puppy. I can pin him on his back and he just plays. I can do things like hand waving with him and he'll get excited, sometimes bare teeth and nip but he does all of this with his tail wagging and not angry.

Sometimes he will bark at me but only for special circumstances in which I've trained him. Such as barking when someone tries to shush him. Lately though, he has taken to barking AT me when I don't throw his ball. I did mistakenly reinforce this by thinking it funny the first few times he did it. Naturally, this emboldened him.

When I do socialize him with other dogs he does not show aggression. Wagging tail, happy to meet you sort of customer. The few times he was in the presence of an alpha male, he burrowed as best he could to avoid them. He did once however try and bite a bulldog's face off because the dog decided my JRT's ears were his lunch. The dog in question, needless to say is VERY aggressive towards other dogs.

He is very aware of what is going on around him. There was once an occasion where 3 pits found their way into my yard while roaming the neighborhood. He didn't nip at them, didn't growl but simply gave them the How do you do? routine. Very happy to see them.

It wasn't until I called him that his manner changed. As soon as I went to separate them he turned and snapped at the pit immediately to my left. The dogs exchanged barks as I pulled him inside.


My initial thought was to maintain him as a stud and not get a second dog. Lately I've been wondering if this move would be the perfect time to add a second dog as my dog, nor any prospective dog I look at, has been to this property.

I know the routine. I am just really interested to see what others think of his temperament in light of what I've written. If he's as mild mannered as I suspect, adding a second dog shouldn't be much of a problem on a new piece of land.

Although there is one other question. Should I already be established at the new place with my existing jack? Will it be better or worse with them entering a strange place at the same time they meet one another? I'm leaning towards the latter but want to get feedback on that.

Thanks.
