I recently purchased a beautiful black sable working line GSD. This is my first one. Prior to this I have dealt primarily with Labs and Boston Terriers. I purchased the GSD for purposes of deterring trespassers from our lake front property. Because we often have family (8yr and 4 yr old grandchildren) and friends I wanted a dog that would be protective but also good with family. After several conversations and research I went with the GSD. I understand that GSDs need a job so I pursued getting a working line (she is medium drive with very sweet personality) in hopes to get her trained in SAR particularly air scent live find. I also have a 4 year old yellow lab and 2 part time Boston Terriers. She has entered into our family with the dogs establishing their hierarchy of dominance and she is submissive to all 3. She loves playing with my lab and vice versa. I just watched a video on the Leerburg website on raising a working puppy and they indicate that the pup should not interact with any other dog so they do not come to find that they can get enjoyment from them as well as me. Also they indicated I should be the only one to feed, play, walk etc..... My girl Anika is now 12 weeks old and I picked her up when she was 8 weeks. She has gone to 3 weeks of puppy class and is a fast learner. I'm afraid that since I have introduced her to my other dogs and have treated her more like a family pet I cannot train her in SAR. I don't think I want her to be detached to people or my family and pets. She is definitely attached to me since I am the primary one who works with her. I suppose my question is - Can you have a SAR or working dog that also is in contact with your family and family pets? If not - what kind of job would keep them happy and social and still make a good family member without the fear of them becoming aggressive due to boredom. Any thoughts on this would be very helpful. We do not have a local SAR K9 unit where I am; however, am working on a certification in SAR for myself. Maybe I should take up hiking or something else with her.
