My new baby boy shih tzu (3 months old) makes nests. Sometimes I'd leave the door to our garden open and he would gather branches, twigs, leaves and make a nest, kinda like a bird's nest. Whenever I close the door to the garden and he can't get out, he'd just gather old towels and used clothes from the laundry basket, and make a circular nest and he'd sit in the middle of it. :(
I have another male shih tzu who is 2 years old, and he never did this when he was born.
Is this normal puppy behavior?

I'm so jel. I love Shih Tzu's!
My Jack Russell used to collect sticks to play with and chew up later but she unfortunately never made nests with them.
What did those scientists do.
Dog Behavior: If it only stays in a mud nest, it is trying to keep cool in the warmth.
Ok never talk about puppies under 1 yr. with me! It makes me puppy crazed! Oh, It's normal!
Until your puppy grows out of this, always keep stuff near by for it to make it's bed how it likes.
