Mine's an 84x37cm glass tank but will be used at two different sizes, there will be a 'wall' down the middle that makes the tank 42x37cm for the nursing weeks then once the pups are all bigger, eyes fully open and being weaned at around 2.5/3 weeks the wall will be removed so that they have full use of the tank. This should give them plenty of space to run off all of that energy they will have but they will be old enough to be able to find their way back to mum and the nest easily
