Relationships/ love

I’m 18 and my boyfriends 20 we have been together for 7months and we are so happy together and we can work though anything. His family love me and my very small circle love him too.

We are at a point in our lives and relationships where we want something that’s ours, we don’t want to put a ring on it just yet but we feel as though it’s time for a step forward.

I want to know if the step we have chosen is totally crazy or it’s a good idea.....

We want to get a puppy🤷🏻‍♀️😊

We have chosen a breed & the sex even the name.

But do we just jump and go for it or not? Plzzz help me
