That being said, the specific wolf (breed, level etc.) doesn't add or change anything to fishing. The only thing to keep in mind is that fishing takes stamina, so you might want to pick one that isn't being used for mining (which also requires stamina), the campaign or the guantlet. Do keep in mind that there is a 24-hour cooldown; e.g. once you have a wolf assigned to fishing you can't switch it to a different one for 24 hours
