We got a 4 month old standard poodle two days ago! His previous owners got him on Valentine’s Day of this year and could not keep him. I do not know his history before then but I assume he was still at the breeder. So far he is thhe BEST dog! He is very timid acting and has been startled by me walking into the room where he is laying and starts barking and growling. He also did this to my three year old child as she ran into the room once. Is this a normal temperament? Something we should be really concerned with or just guide him?
