How many pets do you have?

I have had just one dog and I'm fine with that. Recently I visited a friend and one thing that surprised me was I saw upto three big dogs in his compound. I jokingly asked why keeping all these dogs, he just told me he loves pets that having at least two, male and female is better.

I have three dogs, three goldfish and a hamster. They're quite few for me so I'm deciding to get other ones. They're really lovely though.
