We have a 3 year old blue healer that needs a new home. She is a very protective and playful dog but is not good with other female dogs or strangers that come near the house. We just had a new baby and she is very protective of the baby and my 8 year old son. We are worried she is too protective and may bite one of my sons friends. We feel she just needs to be on a farm or ranch. We have a black lab male that she gets along with great.
