It is wise that you are waiting until a time where a dog fits better in your life. It is important you and your dog have the same energy level. There are strong fast dogs that need lots of attention, and lazy dogs that can be a little easier for someone who is busy. Otherwise you must have space and time, you need to train your dog and learn the language of dogs.
The more you know the better! That dog that you are holding in the photo really looks great! You should see if you can find him again! See if he recognizes you.
Any dog that you ultimately bring into your life will want to work for you, they love to be near by with family and often want to go with you everywhere!
