I don't really consider it training.sounds like you are training her...........?
and doing a fine job of it as well. food is a great motivator. lol
We have working german shepards, we use shock collars for proofing, they search for dead body parts, they do search and rescue, they do high level of obedience.
Sugar is a lazy, mellow dog, with like 3 commands, at the most.
Our working dogs are trained in german and are worked with 15-60minutes per day..... lol so when I think training, I don't think me getting a dog to sit when she feels like listening, as trained haha.

Sugar just does whatever she wants. She's just really mellow. haha

Our working dogs require a lot of training. Sugar, I've spent maybe an hour worth of work, besides walking our property line, and teaching her to come to the word hotdog. LOL
