I think it's better to keep some things the same as in this world. Makes it easier on you and the reader.
Like... Measuring time in hours, days, weeks, months and years for example. Maybe people in another world would do it differently, but it's easier to just use our same system. (though changing the name of the days of the week and the name of the months might actually be a good idea)
Similarly speaking, using the same names we use here for food (well, it might be better to avoid Regional food, but... An apple may still be an apple) and animals is probably for the best... I mean, if you can have an Orc in a fantasy setting, why can't you have a dog? We were the ones that invented the word "Orc" and we also did it for "Dog", there is no need to change one and not the other.
