I’m confused, you are getting a pitbull at some point but want a small dog now? Kinda sounds like it could be a recipe for distaster. If you have owned pits u know how dominant they can be. Additionally a dog of that power and strength do you feel you could restrain it should something happen??
Pitbull out of the picture, I’d say a French bulldog. I have one and they are extremely devoted people pleasers. Love humans. They entrain themselves, just funny loving little animals. Sorry if I sounded negative about pits, I personally am just not a fan of them. But to each their own.
