[GECEDEANY]

I'm looking to have Abbey take the CGC test in the near future because I've really wanted her to get into therapy work. She loves people and has pretty good obedience, but I'm worried about test 8, reaction to another dog. Abbey is aggressive to dogs outside her "pack". She gets along with Bonnie, Bonnie's brother Clyde, and my sister's dog Laine, but other than that, she tries to outright kill any dog she meets. It's not fear, either... she gets quiet, starts shaking, and tries to pull to the other dog. I'm worried that I won't be able to get her to sit still and show "no more than casual interest" in the other dog.

So, I was wondering, does anyone here have a DA dog who managed to get their CGC certification? Any tips on training? Should I maybe save up for an e-collar to train her? She's very soft to correction, so I've only used positive marker training on her so far, but I don't know if that'll be enough to get her past the dog problem.
