Great to hear jpj! Hope you get some nice Tron Dogs!
As far as comparing the ETH to TRX markets, I had a hard time trying to wrap my head around this as well. I think the TRX market might do better only because it's being marketed pretty big by TRON. By saying it'll do better, I'm thinking in terms of volume. You want a market with a lot of buyers to buy up your breeded dogs! We'll have to wait and see :)
As far as buying dogs before a store, they should be two separate businesses. When you own dogs you bought, you should be able to sell the dogs, breed them or maybe like Cryptokitties you can make the dog available to be bred with. When you buy a store, you get packs which contain random dogs that are put on your virtual shelfs for buyers to buy. Those are going to be in a separate section of the website.
I hope this clarifies things for ya!
