How to sell trophys

Okay, you really need to understand more about the game, so I'll give you 2 tips to get money, but first, I'll answer your question.
You can't sell the trophies, but you get money from the competition. This is the case for all of the competitions. There is a thing for the Championship though, where you get a prize item for winning 1st place. That prize item can be sold for a lot of money. For lure coursing, the prize item is Victory Collar, It is a Blue collar with a white stripe going through the middle, a golden medal hangs from the front with the number 1 and the word Dog engraved into it, there are more words but that's all I can work out. All pieces of the victory set sell for $1,500, so It's definitely worth getting them. You can get one per pet, which won't be a problem, because when you sell one item, you can buy another dog, train that dog, win an item, sell it, buy another dog and the cycle continues.
Now, some of this you might know already, but I'll share this anyway.
By the way, The dogs can't breed. This is good, considering they are puppies and, considering this is a game meant for 3+, parents won't want to give ''the talk'' early.
Here's the tips(or cheats...)for making money in N+C
1. There are piggy banks you can get on walks, save before you smash them in your home, keep resetting until you get $100, which is the max. This can be considered a cheat, but A) I call it using your head, and B) This site is called Super Cheats.
2. You can do the same trick as above with competitions, save before entering one and keep resetting until you win. If you can't win, you need to train your dog more.
Hmm, think I put a bit too much information here? I didn't want my answer not posted because I wasn't descriptive enough or too short, but I think I made it too long and hold too much information.
