Thinking of buying a dog. Miniatures need not apply. Pedigree or Mongrel? (Leaning toward adopting an orphaned rescue-centre dog.) Had dogs as a kid, aware of the basics (rectangular, leg in each corner, head one end, tail t'other). Tips/photos/running costs guideline would be appreciated. I feel I owe it to my neighbours to return the favour by leaving neatly tied, little bags of pooh on their garden walls.
