as isaid im looking for an enegretic.lively,athletic dog that will enjoy daily long walks

i have done some dog breed quizes and the best dogs that suits me are:
australian shepherd ( aussie)
springer spaniel
irish setter

i dont know nothing about those breeds exept for irish setter my friend have one they are great dogs need lots of exercise and are very good in temperament they do require lots of grooming thats a fact
i dont want labs and goldens i knwo that they are really amazing dogs loving etc ... but they are not for me
i already have a dog and he will be huge hes a 6 month old GP( great pyrenees) and i want a dog that can hold its own incase that they will get into a fight ( which i dont want)
my puppy currently is attending obedience training classes
