Well when we searched about and investigated, i already had my mind up i wanted one of each. Honey was born first (through my Aunties bitch) And then we found Alfie.
I had decided i didnt want 2 girls, no reason just thought Dog and Bitch would be better, and i have to agree, Honey is the bossiest. Although i only think that because she is the barker. Alfie is quiet, but he is stronger and usually gets his way through being bigger in build. Honey is definately the little madam.
We got ours in May, So toilet training was no problem, but i on the other hand will have the winter for the walks when they are old enough for longer walks.
I think its all personal preference and always got its adv and dis adv what month you bought a puppy.
I completely understand with leaving your kids and a Puppy with someone else. I decided i would not go away without my puppies until they are at least 1 because i dont want to put the burden of 2 young scallywags on someone else !
