ever since the bloodhound dlc came out everyones been asking for more dogs, whether it be more breeds or more 'jobs' like flushing or retrieving birds.
i say yes to new breeds, but i think each dog should be able to do every 'job'. if theres a tracking, flushing, retrieving, and predator chasing/treeing role, with four dogs- bloodhound, german shorthair pointer, golden retriever, and foxhound- a player should be able to buy one dog to do all four roles. thus you only have to spend the money and time on one dog, and be able to do what you want/need with just one dog.
