Kim, I have considered this. He just lays around looking bored, but Im sure there is a lot going thru his mind. He had a few health issues to work thru when we first got him and had also just been neutered. So we really let him rest and heal for the first couple weeks. However, I do plan to continue trying to introduce different forms of play or tug in short intervals at a time. We have him enrolled in a very good dog training too. He's learning basic commands beautifully from that. I understand his becoming comfortable will take time and reinforcement that he is truly a loved member of our family and work on the bonding. I know that will take time. He's very close with us know, and its quite amazing he has been able to do this so quickly. Even the foster mom couldn't believe how quickly he stared bonding with us, the first couple times we went to visit him. She said she had never seen that happen before. We've had several black labs in the past, and they became the most loyal bonded dogs you could ever imagine. Our fur kids are the same as children in the respect that it takes time. I take your input as positive and appreciate your feedback!
