I've been trying to see how much the K-9 pass costs so I can buy that amount of robux. However, if I go to the K-9 Spawner, it says like account not charged or item isn't found. I've been wanting it for a while now and I would love to know where to buy it and how much it costs.

Never mind, found out you have to donate

Hi, in order to use the K9 feature, you must have the Gold subscription which costs 20 dollars a month, you must pay this via USD, you can't pay it with robux. Have a nice day!
