Plum wants a pet. Plum's dad wants NO pets. So Plum, who never takes no for an answer, gets the only pet she can: a pet dad. Dad is a great pet--he loves playtime, tummy rubs, and scratches behind the ears. But every time Plum tries to get him to sit, or fetch, or chase, dad barks NO. Plum doesn't take no for an answer. How will she train her perfect pet (without getting a time-out)?
