I miss my dogs. I grew up with them but now, I don't have a lifestyle that fits having a dog. Can't be out for 10+ hours of the day leaving the dog on its own, it's just not fair on the animal. But I miss that unconditional love and companionship.
You never really understand how much of a part of you they are until they pass. Then you feel the loss of them.
Moral of the story. Enjoy the time you have with your pets. They might only be part of your story, but you are all of theirs.
