I think our chocolate lab, Greta, would "fetch" herself to death.

Yes, I had one like that,Before this one I have now.We would chase each other up and down the hall and she had one toy she would fetch,nothing else.I always had to stop before she did. She was a playful dog The one I have now wants to be pettied all time. Take care of her.

Eventually the pooch will wear out. I have a couple of dogs that were playful, good thing we put them on our sleep schedule.

I have a Boston Terrier and a Rat Terrier, Gus and Cookie, that love to play tug. Gus is a huge BT, they are usually 8-20 pounds but Gus is 37 pounds and all of it is muscle, his head reaches my knee. His jaws are tremendously strong and it's all I can do to keep hold of the toy! Sometimes he gets it away from me. Cookie isn't very strong but she sure can shake her toy. I love my dogs, too! They both also love to chase a laser light. Cookie will chase it in circles till she gets too dizzy and she falls down. I think she enjoys getting dizzy.

I can create a picture of what you are conveying off your lab.i feel all the labs are the same during their active first few years.When we throw them any item to pal y on grounds they run mad and get the thrown item in their mouths and come's out a with a whole load of the dirt and mud.labs run very fast and being so enthusiastic can also get them into some pain off falling cutting and all,but we as do g lovers must take an step forward with their safety.labs are simply so cute and lovely with their facial expressions too.
