Ability to name dogs is good idea. Cows too. Last year i had a mining cow with 1500+ HQ nuggets so i named her Nuggets but i sure wished i'd had a way to tell her apart from the other cows. Naming animals/followers would be great.
In general, "name tags" for sprites would be great. Wallace suggested last year that crafted items could have a "Crafted By" tag, so crafters could get some serious credit. Also i suggested billboards for bases (and tents) so you could tell where you are amongst your vast empire when you first log in. Naming vehicles would help too since that handy key number only works until it is lockpicked, right?
Anyway, not to sabotage your thread - ability to name dogs would be good.
