Progress!
Yes,we are making progress. Abby is now attending obedience classes with the instructor that I have mentioned in earlier posts. We have been going for 3 weeks now.
At last night's session, she behaved like a lady! I had her in a down-stay several times,with other dogs moving around the room. She acted calm when in close proximity to others - not touching, but within 4 feet. I was very pleased.
On the home front, I still keep an eye on Abby when she's around Russell. There are two scenarios that I have to be especially watchful: when new people arrive in my home; and when we ready to go walking. I have actually started telling Russell to move away, rather than get into the small entryway with us.
In the mornings, I walk Abby alone for 2 km, then we swing home, grab Russell's leash and the 3 of us go for a shorter walk. After work, each dog gets 2 km individually. Abby's time is spent training. I read one of your earlier posts about dogs being "situational", and I agree. I practice with Abby in various locations, so that she sits, lies down, stays, etc. no matter where we are. I also use "watch me" frequently, to distract her and get her to refocus when something interesting like a squirrel, bird, or other creature happens to be nearby. It works!
I know we have a long road ahead of us, but we are heading the right direction. Yes, I am aware that I have to maintain my "leader" status with Abby, and with Russell as well. We seem to be there now, and although Abby likes to challenge, she certainly respects me and listens. More and more all the time.
