For context: I’ve never owned a reptile before and really would like to start my adventure with a bearded dragon. I’m keen on red monster BD. I have a few questions.

1, what size vivarium do I need?

2, what do I need to feed it?

3, is there a vivid difference between keeping a male or female?

4, shall I get a baby or adult?

5, I’ve got a small dog, is this an issue?

Thanks for your help
