Učestalim izvođenjem za fotić trogodišnji je Tuna postao pravi celebrity. Zbog krivog zagriza slaže nebrojene grimase koje su ljudi ispravno naučili smatrati unikatnima, a ne ružnima :)
Phteven is a nickname given to Tuna, a chihuahua-dachsund mix with a prominent overbite and lower jaw dysfunction, who became after his owner launched an Instagram feed in November 2011. The nickname comes from an unrelated image of a receipt with the customer’s name misspelled as “Phteven,” or “Steven” when spoken with a lisp.
