Plse help we just got a German shepherd female puppy 3 weeks ago and she likes to chew and we get that she is teething but she chases my todler around and either jumps on him to play but mostly chases to bite mainly his legs and my todler cries out then I tell her NO BITE ! And if she can't be redirected with a toy I put her in timeout but she doesn't stop even with me and my husband and older kids. She even tried to nip when I disapline her all she does is bark and do what I called air bites when I hold out my finger and tell her NO but she barks and tries to nip. Help what can I do so we can live peaceful and so the baby won't get hurt
