A little background:
The orginal owners bought her at 8 weeks old. They had 4 young kids and left her outside or penned in the laundry room a lot.
My Mom adopted her at 4 months. She was a real terror, but my mom did training school w/ her and she showed some improvement. My mom was home w/ her a lot. Unfortunately, my Mom developed cancer and passed away when the dog was three. For the next two years, she was home alone all day (with the exception of my sis or I stopping by on our lunch break to let her out) because my Dad worked from 7-6. She did have a crate the whole time she was living there, but if she was shut in it, she howled much worse.
Two years ago, I 'adopted' the dog and brought her to live with me. She doesn't bark or howl as long as I'm home, but all the neighbors says she howls when I'm not there. I'm home with her most of the day, typically. She's always been very needy with all her owners...following them from room to room, wanting to 'cuddle'. She's very big on affection. She is fully housetrained, and has never chewed or destroyed anything.
Since I've owned her, I take her for at least one long walk every day, and I try to do it right before I leave. She's very well behaved on walks. I also 'play' with her during the day. I really can't exercise her more than I already do, as I have an auto-immune disorder that limits my exercising. I've tried the Kong toys etc, and I always leave the tv on. I've left a tape recorder on when I leave the house to monitor her. From what I can tell, she starts howling as soon as she's gotten the treats out of the toys! I've read up on all the behavoiral techniques on Seperation anxiety (leaving for a few min and coming back, etc), but nothing has worked thus far. Typically I'm only out for an hour or two, as I work from home. At the most, I leave her for a few hours to see a movie, etc.
I know that Springers are needy and prone to separation anxiety. I'm not sure what else to do? Any thoughts? Thanks for your help!
