Finding either a free adult pug or a free puppy may not be nearly as hard as you think. Now if you're looking for a specific breed for show or breeding purposes, then that's an entirely different story, but if you're looking for a good family job, then you have a lot of options.
In the country, it's not uncommon for a farmer or some families to let their DOGS roam outside. While this is great for the DOGS, it also leads to a lot of pregnancies and liters of puppies that the family may not want.
While most dogs shed, poodles are actually incapable of shedding. That fact makes them excellent house pets, since they don't get the furniture covered in fur. Also, due to the nature of their fur and the fact that they do not shed, most people with dog allergies aren't allergic to poodles.
Sometimes a hunter will want one or two puppies from a good hunting DOG, but not necessarily the others. Asking around, or paying attention to small town newspapers will often lead you to families who are looking to give away free puppies, or even older pugs. It's not uncommon to get pugs who are several months old because the family couldn't find homes for all the puppies. Sometimes this is even a better option because these pugs may be used to children or house broken.
Also pay attention when people are making a major move. If your neighbors have a sweet pug, but are moving from a town to a cramped apartment in a huge city, then they might very well rather see their sweet pug in a good home rather than at a shelter, and if the pug at least knows you, this could ease the burden a little bit for you and the new pet.
While adult dalmations are covered in cute black spots, dalmation puppies are actually born solid white. Their spots don't show up until they are at least a week old. Sometimes not until they are a month old.
There are always people looking for good homes for their puppies and DOGS, so just keep an eye open and ear to the ground, and you are sure to come up with some great options for your new pet without having to spend a penny.
