Our Berner, Koda, is mostly the perfect dog. We got her the same day we found out we were expecting our fourth baby. It was bad timing - morning sickness with house-training a berner. Her first 9 months consisted of me sick, trying to train her, then I was on bedrest for 11 weeks, then our baby was in the NICU for 23 days. For that time, we were in survival mode. Koda laid around, staying close to me. When we basically lived at the hospital while our baby was there, we had lots of family and friends taking care of our 3 other kids. Since then, Koda has been very deffensive of our family and home. If someone knocks, she will bark and growl. If they come in the house, she will growl softly for a long while, and try to stand / sit in front of me - making sure she's between me and the person. I don't let her, I gently correct her, and make her move. If she won't calm down, I have her go in her kennel. If they try to offer their hand to let her sniff it, she jumps away from them. She's the same way with other dogs. We've tried having new people offer treats, we've tried ringing the doorbell over and over to get her used to the sound, we've tried endless corrections. We've had doggy play dates - she doesn't seem to ever relax and just have fun or be curious. She acts frienlier to the vacuum ... which shes not very fond of! We had a large family gathering last week, and had Koda in her kennel for 2 hours before the toddler let her out, and I was supprised because she just went around and was friendly to everyone. It was awesome! But, the next day she was back to normal ... growling at my brother who had been there the night before. She just doesn't trust people ... she's AMAZING with our family and our kids ... but she isn't friendly to anyone else. She's also not just aloof ... she's fearful. Its not breeding ---- both her parents were awesome and sweet and friendly, and all her 9 siblings aren't having this trouble - they are all really friendly and outgoing. So, its not genetics, its from US. What should we try? Any advice? I feel like I've failed her by being so sick and uninvolved during her first year, such a developmentally important time. What can I do at this point? Can I help her get over her fears? Any reccomendations? Honeslty, besides this issue, she's soooo perfect. She adores our family, is gentle with our 4 kids - even the baby, and is just so sweet and loving and obedient. Its just when others come around!!! I'd love to help her through this so she can be the 100%-perfect dog for our family! Thanks so much in advance!
