We rescued Rex from not eating for 3 days, mostly crated, no running, just inside a small house & even was let to potty in the house! We've had him 3 months. We've been renting a small house for 6 years but they decided to sell & we have to be out by October 1st so we are in urgent need to rehome him even though we want to keep him forever. He's come a long way in a short time. He's VERY loving & cuddley! He's friends with my oldest cat but the younger one won't give him a chance. He LOVES kids as he was in a home with a little one previously. I've seen no aggression at all just some separation anxiety but if he had the room he needed to work, I don't even think he'd have that. He has marked in the house a handful of times but has made progress. He's full of personality & pretty vocal. I can't tell if he's a mix or not but maybe German shepherd. I've never had to do this. Our hearts hurt but we have to find him a forever home because the beginning of his life has not been very fulfilling. We walk him every night & take him to dog parks. He loves other dogs! Ask any questions!
