Get a Kilian mug for your dog Riley.
Rare Irish name so will inevitably be coupled with a stereotypical paddy surname and a heavy drinker! People with this name are usually, more often than not, complete and utter legends!

Kilian can be crazy sometimes, but he is always caring. He wants to help, but can sometimes get carried away. Kilian also is kind of annoying, but he is confident in what he does. If you know a Kilian, lucky you! You might just, if you're lucky, get him. If you do get him, you better keep him.
Always remember, never underestimate Kilian.
