Two Chihuahuas Puppies

I very much want to buy two male (or male and female) short hair Chihuahua puppies, preferably like the two dogs in the photograph that used to be my pets.
I will also consider any age Chihuahuas that are well housed trained and are independent.
I live alone in a secure flat in central London with access to a communal garden.
They will benefit from a lot of love and affection from me and will be well looked after as I have previous experience of keeping Chihuahuas in the past.
