Hello everyone

I am wanting to make a puppy pen outside on my patio area so that the pups can have more of a run than they do at the moment, also it will give mum more of a break as she will be able to get in and out when she want (at the moment the puppy pen is redundant as the pups can now get over the edge too) I have a massive crate for them all to be in but it means that Fey is there anything I need to take into consideration?

I know it needs to be secure, have somewhere for them to go to if they want a nap,

Does the patio need to be sterile?

Help lol

I am being mugged by 4 bouncing boys everytime I feed or clean them lol
