I have 3 dogs (Father and his son and daughter) and I love all 3 of my dogs. My favorite is Lassie because we have a very strong bond - she follows me EVERYWHERE. All 3 dogs are Rottweiler/Labrador mixes and are extremely intelligent but she is the most intelligent one. She nags me when she isn't satisfied with something and she is a very loving dog who is always in a playful mood. The funny part of the story is that years ago when I was living with my mother, we gave her away to someone living halfway across the community from my mother. She was 4 weeks old at the time and we didn't have anywhere to keep her. Needless to say, she found her way back to us 3 weeks later and she gave my mom an earful because my mother was the one that gave her away.
Our neighbor couldn't contain her laughter when she saw Lassie grumbling and complaining. Animals are very good teachers of loyalty and unconditional love and we can learn a lot from them.
