most animal shelters make sure that their animals have regular check - ups with veterinarians.
another mistaken belief about adopting dogs from shelters is that you cant choose a specific breed. when you buy a dog from a breeder, you can get exactly the kind of dog you want. its true that many dogs available for adoption are a mix of two or more breeds, not purebreds. but shelters accept all breeds of dogs. if you want a particular breed, chances are good that one will turn up at a nearby shelter sooner or later. you can also consult a variety of rescue shelters that find new homes for particular breeds. dog lovers can adopt from specialized organizations such as greyhounds only, collie rescue, inc., and chihuahua and small dog rescue. with so many options, adopting a dog doesnt have to mean giving up on your dream breed.
there are hundreds of thousands of dogs stuck indefinitely in shelters through no fault of their own. if you are ready to make a lifelong commitment to a canine companion, rescue one of these dogs. youll feel good about your choice, and so will your dog

Explanation:

The author includes the fact that there are "hundreds of thousands of dogs" in shelters to create a sense of urgency. When readers know there are so many dogs stuck indefinitely (through no fault of their own), it makes them feel that urgent action (like adoption) is needed. The other options don't fit - it's not about sharing info excitedly, reducing confusion about numbers (the key is the large quantity creating a need for action), or making readers feel relieved (the word "stuck indefinitely" implies a problem that needs solving, not relief).

Answer:

To make the reader feel convinced that urgent action is needed.
