You got great advice on crate training or x-pen when you're gone - then when they're older use the gate. Mine are gated into the kitchen when I'm gone and they do great/
That would be great if the breeder will keep your little one a bit longer. The socialization that occurs after 8 weeks with the mother and litter mates is very important
