Enoch is 4 and half months old. The only dogs he has been around are his sire, dam and grandsire. My breeder also has another GSD and a JRT. He played with them well and seemed to enjoy himself. Today at the park I ran into an acquaintance who had a 4 month old Bulldog. Enoch sniffed her and then he backed away. He would go up to her again and back away as if he was scared. He wasn't scared at all of the owner but he seemed to be timid around the dog. Now, I don't care for him to play with other dogs necessarily but I also don't want him to act fearful when other dogs are around. The one hopeful thing was although he would back away he kept coming up to her and sniffing. Any thoughts or suggestions?
