Things to Think about before adopting  a Dog

1. They shed.
Yes, they have a short light coat. Yes, they are easy to groom and maintain. But they are dogs and like every other breed that has fur they do shed. They shed lightly, but they do shed. Get used to it or get a stuffed toy. If you don't think you can become accustomed to thinking of dog hair as a condiment, don't get a real animal.
2. No matter how gentle Greyhounds look, they are still large to very large dogs.
An overly excited, untrained 45-95 pound Greyhound may knock down smaller children or a a frail person. And Greyhounds tend to hold their ears back and their tails tucked and balk when they are stressed. Folks that don't know the breed might mistake this for aggression and find it too frightening to live with --especially in a dog this large.
3. Dogs and lawns are not a great combo.
Unless you have a very large yard that you can section off so your dog has his own area, it isn't likely that you can have a great lawn and a greyt dog. Get used to it or get a cat so you can use a litterbox. Greyhounds love to run and while they don't need a lot of exercise, when they run they will destroy your landscaping. If gardening is your passion, a dog who loves to run may not be your best choice.
4. Dogs make messes.
Even the best mannered, best trained dog gets sick. and if he gets sick, he isn't going to rush to the kitchen or the bathroom or some other easy to clean surface. The rugs are where the traction is--that's where he'll barf. Even elegant-looking dogs like Greyhounds get gas, barf, and/or get diarrhea at some time in their lives. Dogs track in dirt. Dogs and fancy furnishings, expensive rugs, and elegant decor aren't a good mix. If you can't stand a little dirt and fur, if fancy things are really important to you, or if your life's dream is replacing Martha Stewart, don't get a dog--even a quiet, clean dog like a Greyhound.
5. Greyhounds love (and need) soft, warm places.
If you want a dog that you can house outdoors or if you can't stand the idea of a dog on your bed or furniture, this is not the breed for you. Greyhounds are not suited to living outdoors and those bony joints need padding and a soft, warm place to rest.
6. If you don't have time for a child, chances are you don't have time for a dog.
If you have children and all your time is spent at soccer games and school activities, unless your Greyhound can be part of the activities, you don't have time for a dog. Dogs are social animals that need physical and mental stimulation. And just because they are quiet, gentle dogs, doesn't mean they don't need to be trained. Training isn't about obedience as much as it's about forming a trusting relationship and establishing a way to communicate.
7. Dogs and children are not as compatible as Hollywood would have you believe.
Greyhounds have little padding and they have skin that tears easily. They have little protection from falling toddlers or rowdy children. They have a quiet nature and do best in a tranquil environment. If any of your children are under school age or your kids are particularly active, don't get a Greyhound.

I'd even go a step farther and tell you don't get any adult dog if you have young children. Dog bites are one of the leading causes of injury and death in children. And I can assure you, biting a child is a leading cause of death in dogs. If you insist on combining children and dogs, research breeds very carefully and commit yourself to learning and taking all the steps necessary to make the combination work.
8. Just because your lifestyle and interests change doesn't mean you can abandon
     a dog like a used toy.
Divorces, job changes, relocations, and new babies happen. If you can't be as close to certain as humanly possible that your retired racer will be part of your life for all of his life, don't adopt.
9. Greyhounds are easy to live with but they do have special needs.
Their lack of body fat, long thin bones, fragile skin, and sensitive souls means they need to be protected from extremes of temperature, rough environments, and inappropriate handling. Thousands of years of breeding to build quick reaction times, create blazing speed, and to foster working away from and independent of human direction, meaning they must be kept safely in fenced areas or on leash at all times.
10. Adding a retired racer should never be an impulsive gesture.
Don't adopt because you feel sorry for them or because it's fashionable. To paraphrase a bumper sticker from the Association of Pet Dog Trainers, A dog isn't just for Christmas. It's for life.
