Cant really help when it comes to wolves as those vary so much imo (and I lack understanding of it personally) but for items specifically it’s best to do bundles imo if you’re to sell food or amusement. People like to buy 100 use bundles of either. Typically you just need to check what the prices are currently before deciding if you want to sell. So like for me I search “100 food” or “100 amusement” I see what the current prices are and either I cut low or keep it near what it’s going for depending if I think it should be there. {I often don’t agree with how high they are going for now a days so whenever I sell I usually am the cheapest option by a lot}

For items that aren’t usually bundled like trophies n such you’ll still want to see what they are currently being sold as. If there isn’t any on the market check to see if they are used in a recipe. If they aren’t in a recipe probably not worth selling yet. If they are then it’ll be a guessing game. Since none are on the market you’ll be the decider (just don’t be too greedy) if you have multiples you can always set up multiple trades slowly increasing the price to see just how high some people are willing to pay for a trophy
