Growing

I have started to get my Big Dog coat. Long hairs on my ears, tail and legs and there are lots of new long hair on my body. Kathy keeps combing out the puppy fur, but there is still lots of it left.
I got a new ball a few days ago. It rolls about, but it also has handles all over it so I can get my teeth into it. K&K keep throwing it away then tell me to fetch it. I do a few times, but if they really want it, why do they keep throwing it away?
We have been to lots of new places where I can explore and meet new people and dogs. The trouble is, after about twenty minutes I have to have a lie down for a while.
