Breeders so not like to ahve two young pups in the same home as it usually means that they bond too much with each other and are a lot harder to train. It really isn't troubel doubled it is squared :D
You should wait untilyour current pup grows up and is well trained before bringing in anew pup, it will make life a lot easier for you and also there is less chance the pups will fight when mature as the younger one will normally accept the adult as boss, whereas two pups one will want to assert itself over the other when mature, and if they both do it will lead to fighting.
