we have a 3 legged dog called oscar and we have had him for 7 yrs, we recently got a puppy (bichon frise) from a rescue centre, we took oscar with us on the initial look at angel, since we have her home now oscar is acting very strange with her, growling at her, been very jealous, taking her toys into his bed etc, he wont interact with her at all, i would be very grateful for any help as to how to get oscar to get along with angel.
