One of my roommates has an 18 month old female huskador. She's been tearing/chewing up stuff for the last several months and it is becoming a huge problem as it's amounting to hundreds of dollars worth of items. He feeds her once a day about 2 or 3 cups. He only takes her on walks maybe once every two weeks. I thought she needed to get out energy, but one time she tore the couch stuffing out right after we got home from a 20 minute walk. Help!!
