I will definitely let you know exactly what they find out.
Right now they are suspecting she has a very high prey drive. I think someone here mentioned that might be the case. It might have been Ddski5 (sorry I don't know how to tag here). Combined with anxiety.
This is the whole line/breeding part I'll try to explain without sounding like Game of Thrones lol
Her trainers are the owners of her grandparents on her dad's side, and also have their own breeding program (we'll call them T&B). Originally, Eris' dam was going to be part of T&B's program, but they didnt end up proceeding with breeding her due to her poor temperament. The female was a neurotic reactive mess. That female was owned by someone else we'll call "D". D ended up eventually getting a male from T&B. That male went on to be bred with the neurotic female, and that's where we got Eris. Eris also had a sibling with a severe deformity too, so yknow, idk man. T&B maintains their biggest regret was ever selling one of their dogs to D b/c now their lines are linked, and they don't like D's program at all.
What they said on the phone was that it's sounding a LOT like Eris is maturing into being like her mom. The difference is, they breed their dogs for working drive and sporting. So they're wondering if she got a wombo combo of extremely intense drive from the sire and the neuroticism from the dam, which is going to make her atypically difficult, definitely not a good first-time doberman experience.
Her "aggression" may be coming from her insecurity and nerves, but her obsessiveness over chasing the cats, children, little dogs, etc sounds like high prey drive. Then us punishing her for engaging in this drive is confusing and frustrating her, so managing it is really hard. She may need to be put into some kind of activity that gives her an outlet, such as a sport or a full time job, and if that's the case, they will try to help find that outlet. They also confirmed they saw her be sensitive towards the ecollar, so when I explained the eCollar situation, they said that sometimes that does happen and it sucks, but understandable. She may have associated the eCollar sensation with other dogs, and it's led to the aggression (but its just our running theory).
Ultimately she might do better in a different environment, but they said the goal first is to get her good to come back home with me. IFFFF that's not a good option, they will help us figure out alternatives. We just don't know yet.
We all know she's a good dog, but they are in the boat that this is just her personality, and there's not going to be any changing her. What we might be able to do is manage it and/or find her a situation that lends better to her personality, but we cant change what kind of Dobie she is.
So that's all I got for now. All we can do is see how she is when I get her back. She will go to them on May 12th and I should get her back sometime after the 24th.
Thank you again for all the support, amazing questions, ideas, theories, stories, etc. It's why I came here in the first place.
