There are several things to consider before choosing a dog, especially if you have a family, as there are other variables to consider. First, the most important question to ask yourself is how much room will I have for my dog? Do you live in an apartment or condo with a small piece of concrete as your front yard, or do you have a house with a large background? Then ask yourself how many hours a day you will be gone from the home.
As an owner of a small dog, I have lived in both an apartment and condominium, both of which have a small yard. I intentionally did not get a larger animal because I knew that it would be unfair to him. If you live in either a apartment or condo, take into consideration the space you live between your neighbors. Do they like dogs? Believe me, I got an education real fast when I moved into my first home. The first week I moved in, I received a nasty note in my mailbox from my neighbors about my dogs barking. Several weeks later I was more than happy to get a dog walker, but it created a tension between myself and them ever since.
It will also be instructive to spend some time with your pet of choice. This will allow you to see if there is a bond that develops and also to see what type of behavior the animal has. Do you have allergies and is this a problem? How about your friends and family? It can be hard if someone in the family is allergic and can not stop by your home. The same goes for friends, and it can greatly impact your life by not having friends or family over.
A pet is not something to take lightly. For most of us, it is a member of our family and will be with us for many years. By asking these questions, it will help guide you in determining what kind of breed fits in your lifestyle. Good luck to you. May you have many years of happiness with your new family member.
