So finally our Heidi is home. She is 7 weeks. Stereotypical gsd puppy. Whole 9 yards. Best thing ever after the loss of our Bella. Anyway, most of it is coming back to me except some stuff which I have forgotten in these 12 yrs. current question- how much leash walking is too much or too little?. We have a mammoth yard & have already started very basic commands, come, go, run( hop)!etc. But how many times a day can she walk on leash & how many minutes a time? 5.. or...? Thank you in advance guys!!
