I've posted a page on the site on Italian dog names as I know that sometimes it can be hard thinking up new names for your pet. There are a few hundred in alphabetical order with pronunciation tips, so I hope it gives you a bit of inspiration. Let me know if you want any added to the list. And of course they aren't just for dogs!
My own dogs are called ZsaZsa, Maia and Gaspare (Gas or Gassie for short). What about yours?
