Ours is 190lbs now. Laziest dog ever in fact we wanted XXL for the laziness. Sleeps in every day, is content with one big walk a day where we let him sniff & smell to his hearts content and he gets his outdoor lounging time in a fenced in yard esp in this weather. Over 120lbs the meds for flea/tick do go up in $ since they only make then for dogs that size. He gets 2 pills a month vs 1 for a smaller dog. Food is a large bag every 3-4wks since he only has 3 cups a day plus cheese tax. Now XXL do have a shorter life span 8-13, our guy is turning 9 next month and outside of his Addison's disease which is controlled with meds he's doing great. I've seen some similar go beyond. He is a mix (St Bernard/Dane) so that may help.
