What are Boosters?
Boosters are items that give your Dog an advantage in the game in different ways. Some increase a dog's experience points, some give it more stats than normal items, others may Boost happiness, decrease age, or other types of effects. Most booster items are released around holidays or the site birthday and so are considered "rare items" on the game. Some are more common and can be found through other means.

How can I use a booster item on my dog?
If you have a booster item in your inventory, just click it and a list of dogs you can use it on will appear! Some booster items require your dogs to be at least a certain Level before you can use them. However, a dog can only have a maximum of FIVE boosters used on it! Once you use five on a dog, no more can be used on that dog, so pick and choose carefully what you want to do!

How can I tell how many boosters have been used on a dog?
You can check how many boosters a dog has had used on it by going to its "About" page. Near the bottom of the table of information, a line in the table says "Boosters Used:" followed by a number out of five (for example, 1/5). So long as it does not say "5/5," another booster can be used on that dog.

Event boosters
Boosters are typically released as part of an event celebration, and can sometimes be found for sale in the Fame Shop or at Bob Hans' Trading Post.
