<human>: Hey all! 

I have a 1 and a half year old black lab-Pyrenees cross who has no interest in toys at all. Overall he's a fairly laid back dog, definitely from the Pyrenees, and prefers to sit or lay/sleep by my side where ever I am. He follows me around the house constantly which, though is cute, can be really annoying. When he lays beside me that's all he does as well and I'm concerned he's not getting enough stimulation.

We have a very energetic puppy as well and they play outside a lot and I do walk him everyday so he does get exercise but he doesn't do anything while inside. I thought perhaps because he's so large he just gets more tired out from activities, but every now and then I'll find something (usually a cord or a shoe) chewed up by him even though he has toys of his own.

I've given him tennis ball material toys, hard chew bones, hard rubber bones, balls, stuffed toys, and ropes but he has no care for them. I've tried praising him when he looks at it, and when he picks up the toy in order to encourage him to play with it, though he always just drops the toy and then never looks at it again. 

He does love food type chews such as rawhides, but I don't want to give him only this stuff because I doubt it's healthy to do so.

Give me a shortened version of the text
<bot>: My dog doesn't have interest in any toys that aren't cords,  shoes, or food and spends all his time inside sleeping, how can I get him stimulated while inside?
