Ever since I moved out and left my old pal, I've really been wanting a dog. My apartment requires that it be at least a year old, no more than 50 lbs. and spayed/neutered. I don't know if it's best to go to shelters or buy from a breeder. I went to the humane society today and walked some really chilled ones and some crazy ones. I can't spend too much money and it's hard choosing a dog that I can leave alone as I'm pretty busy during the week. Anyone have any suggestions or tips on selecting a dog? Thanks.
