Please don't outrule animal shelters to find a dog for your grandmother. First take into consideration that animal shelters have mostly adult dogs and with an adult dog you do know how big it will be because it is already there . Second, an adult dog may be a much better choice for an older person, who may not want to deal with the antics of puppyhood. I saw a darling white poodle at an animal shelter a week ago. As the dogs they have change frequently, you might want to stop in every week to see what is up. The cost of adopting is usually very reasonable.
