Socialization is at the top of her list, thank goodness, and little Jacque is learning well. She visits the dog park with him regularly and he has proven to be a confident and well-mannered playmate for most of the dogs. He is still working on his vocalization, though. That's a nice way of saying that he needs to bark a bit less.
The many challenges of a new puppy have given mom a new sense of purpose in her life, and she is enjoying this immensely. Many senior citizens who are able to care for a pet, find that this responsibility breathes new life and energy into their days. A host of new tasks and challenges await and each one is a new adventure.
With many dogs available for adoption through shelters, at little cost to the owner, a senior citizen, on a fixed income can often afford to adopt a smaller dog, whose food requirements will be considerably less than my 4-cup-a-day Golden Retriever. A minimum investment of a crate and vaccinations necessary for good health can bring a lonely person a sense of importance in their new job of nurturing a dog.
Adopting a mature dog can often mean that the task of house-training is already accomplished. Even more, that puppy hood trait of chewing everything in sight is often also a thing of the past. With a daily walk, adult dogs can find happiness with a new owner who gives them the appropriate discipline, rules and finally...affection.
The latter is good for both dog and owner, but the whole package is necessary for a dog to become a bonded member of the new family. Take the lead and show your furry friend the boundaries of his new home, and he will become a good companion.
For a bit more information on bringing home a new family member, I like this DVD by Cesar Millan. His approach involves more leadership than training, and is very no-nonsense. Good luck!
