um, actually, any dog can be kept in a high rise. my fren has a husky and rottweiler in his apartment just as long as they get their require daily exercise it shd be fine.. but one thing abt condos in malaysia is that pets are not allowed at all. All it will need is just a single complain (cld be from ur dog or any of d residents pet) to drive everyone's pets out. its definitely a risk to take. pls reconsider and it wld be wise to check with ur management and neighbours, just in case.
