Right now, I am looking at a couple of breeders, knowing that it will be at least another year before I am ready for a second dog.
Having said that, if the right dog comes along in my friend's rescue, I wouldn't turn it away. It's harder for me to go rescue now than it was with Meg, because I think I'm going to need to go with a young puppy (under 4 months) for her sake, and I'm not sure I trust myself to be able to read such a young puppy for the traits I want. I'm much more comfortable picking out an adult dog! I figure if I go with a breeder, I may get more help in that department.
