Growing up sheltie

We is 10 weeks old now and mom says we are so smart.... we can already do sit, stay, shake paw, lay down and come ! She has been taking us walkies and says we are doing so good....we walk at her side and sit when she tells us......but those darn leaves falling off the trees get us every time.....we LOVE dry leaves ...they are the bestest ever toy and we love pouncing on them....but mom doesn’t like us playing with them...she is scared they will make us sick. Moms are such worriers.
