I wouldn't give up to quickly. It takes my dog Nova at least a month to get used to a new dog. Try to get the dogs together on play dates, twice a week for 4 weeks. Then try to move them in together. Play dates can be going to the park. Going to the pet store. Going for a walk, anything that is fun for the dogs to do. *Make sure it is on neutral teritory* (the park, a diffrent neighborhood etc.)
