Hi we have 2 dogs now. Both are 3 years old. Our boxer is a female and the other is a Bichon Frise who is male. We found a very sad and lonely 4 year old male who was surrendered at our local shelter. No wiggle, no kisses, head hung low, looked very broken and sad. He has been there since September. Our heart says to help him. What are your thoughts of bringing in a third dog who is male? He looked to be a farm dog and has been around alot of animals with no problems. The paper work did say protective of his owner, but VERY friendly. He is so skinny. So are mine but his body doesn't match his head. I am looking for some advice about the males getting along. I won't endanger our Bichon.
