Wow, for some reason I stopped getting emails when ppl replied to this thread!
Im glad this set off to such a productive discussion!
Well, here's an awesome little update:
Princess Zelda has become accustomed to my voice and my commands! When she's in the yard, anywhere in the house, exploring within the gated complex just outside my girlfriend's apartment, or in a small park off-leash, she will usually come back to me the first time I call her! If we have just gotten outside and she hasn't had her fill of sniffing and eyeballing her surroundings, she generally wont come running, but she will stop dead in her tracks, turn 90?, and continue looking around. Im absolutely ecstatic that my 2 year old female Basenji / Red Heeler is so dang smart!
My GF and I went camping recently and we brought out furry friends (she has a 4-5 month old beautiful brindle pit / lab mix). I bought a metal corkscrew stake and a wire tether to keep her close at the campsite, and she constantly wrapped herself up comically to a point where she would just give up and lie down, lol. When we went on walks, however, I brought a 30 foot non-retractable leash to drag behind her (so i could step on it and verbally recall her when she got too far away) and she learned almost INSTANTLY how far she could go before I made her come back. After about 3-5 times, she began responding to my voice alone!
So yeah, there you have it! She's doing absolutely great and learning so quickly! She has quickly become the dog of my dreams, and has completely given up her home-alone chewing habits, so I no longer have to keep her locked up in my room when I'm at work. (it probably helps now that I have a roommate with a 2 year old Blue Heeler).
The only problem I seem to need to deal with now is her habit of pulling cat poo out of the litter box and leaving it on my new rug! :-0
