A steady adult dog of known history (although never left unattended with a child under 6 years old) is a good choice. Children under 5 are very touch on dogs - eye level, fast moving and not respectful of "personal space". Very careful choice of an individual dog is very important.
A dog can be the best thing for a family or the worst for the dog and the family. Being patient is critical both in choice and once you get a dog home. A consultation can be set up at your convenience to discuss your needs.
Senior dogs are often overlooked for puppies or younger dogs. They are generally the easiest to come into your home and still bond with you quickly. Seniors are an excellent choice for a first time dog in your life. Many seniors lose their owners and are catapulted into a stressful shelter environment - dazed and confused many times they become depressed.
Many are well-trained, housebroken and have vet procedures up to date. They are quiet in the home and are content to be couch potatoes. In many cases they are a great choice for senior people that want companionship but are unable to do advance training or hve physical constraints for activity. Many small breed seniors live well into their teens in good health.
A senior dog is generally a pleasure to live with, they will need a patient adjustment period, but it is well worth it.
Again, if you have any questions about which age is right for you, a consultation can be set up and I can answer your questions for you, and help you to make the right choice for your home.
