Hi! I could really use your advice on this one and I need to apologize for the lengths of this post. I am so overwhelmed and I guess I need help but I haven’t figured out what kind… Private trainer? Forec-free 2 week doggy bootcamp?? Is is too late already? With our male Lab-Mix (10 and fixed), our male BMD (2 and intact) and our smallest, a female Border Collie Mix (1.5 and spayed) our little family was perfect. Then my husband heard about a young female Bernese in urgent need of a new home and he couldn't resist. She was about 14 months when we took her in this February and her story was told as follows: First owners’ other dogs did not like her so owner built 10x10 outside where she lived for the most part of her first year till owner number 2 “rescued” her but now they couldn’t keep her because the house was too small, not enough time, new baby on the way etc. (How I love hearing stuff like that….). We were told she was very submissive and “a bit rough around the edges”. Right away one thing was clear: She was afraid of people and afraid of other dogs. I also learned that she wasn’t really housebroken. Sounds like fun, right? We introduced her carefully to our dogs and to our friends and she managed to overcome her fears amazingly fast (within 3 weeks she would walk up to other people) but she went from afraid to shy and then after her first heat to aggressive towards her siblings. Our biggest issue is that she doesn’t seem to have any impulse control: If something irritates her even the slightest bit she starts beating up on her little Border Collie sister. She will even go look for her to attack her. While she doesn’t go for a kill she bites hard enough to draw blood and it seems she can’t stop. She also attacked our male BMD twice. She will give warnings (she stiffens and she has this almost high pitched growl without showing teeth) but my husband feels that she is like a powder keg – ready to explode at any time without any reason. We thought exercising her would make her more mellow but it is sooo hot here in Illinois that she really hates to be outside so running her or playing hard in the yard to get rid of some energy was not an option. After taking her to a drafting workshop (just to see if this would be something we could try later on) I was convinced she really had a strange way to walk so I took her to an orthopedic specialist and had her X-rayed … $300 later I now know that she has elbow dysplasia and she already has clearly visible arthritic changes at 18 months. So no drafting in her future and the vet advised against agility also. Since she wasn’t spayed I wanted to wait with that till she is fully grown but now I after her going through her second false pregnancy I changed my mind. With her elbows there can never be and “OOPS” so we will have her fixed within the next month. Since I luckily work from home I can watch my little pack 24/7 and when I have to leave the house I leave her in a separate room and she goes in it with no complaints. I try to take her mind of whatever is bothering her when she gets into her “moods” and it seems to work. It is surprisingly easy to "bring her back to normal", a little "look what I got here" or "where is my pretty girl" or "let's go outside" works just fine. But this is no solution for my problem because she still gets “irritated” to begin with. Little things like she finished her rawhide early and another dog still has a piece left (she will not attack that dog though), a weird sound, any stressed vibes from us … the smallest things we don’t even notice… will get her going. The worst is if she gets “yelled at” from one of the males because she stepped on them or gets caught trying to steal from them – then she can’t get to our Collie fast enough to “work off her frustration”. I think she was never properly socialized as a puppy (makes sense if she was in that 10'x10' pen 24/7 as I was told) and I hope she can overcome her issues. I really don’t want her to have to go to owner number 4. She is my cuddle-bug, she learns sooo fast, and 99% of the time she and her Collie sister are almost inseparably; they play and sleep together and when I come home the Collie leads me right to the door of the room where her sister is kept so I let her out… It’s sometimes hard for me to understand how much the little one still loves her big sister despite all these outbursts. Any ideas??? Thanks!!!
