you can carry them in pet carrier if you need it i had few of them defending my wooden cottage in forest they were nice agaist zombie dogs and other lone hostilies i just had to put them in pet carriers when i was home they mostly stayed near it so i just put them in pet carriers when i had to go on looting
alslo i think that pet carriers should be craftable, we can make complicated pneumatic weapons, gauss weapons, swords and armors but we cant make cage or pet carrier
and pet carrier do not look complicated too, a survivor without plastic mold can alslo use steel in place of plastic to make makeshift one anyway
