That's one handsome bugger u got there! Long haired, is he? I usually take Kaiser out twice a day for roughly 15 mins.. Since he's not had his shots yet, I just take him up to the terrace of my apartment building.. he's about 8 weeks old now.. maybe another month or two & I'll start taking him out.. I would suggest see how tired he is after his walks, if he crashes as he enters home, that's good, if he still has some energy to burn, increase the duration in the next walk period..
