Hi All, I have posted before about Diva's biting and had some good advice from some of you, but I felt I had to post once again as after a respite period, Diva is back on the biting game

!!! She is ok most of the time but she sometimes lashes out, mostly at me

, and it is no fun! Let me explain: we went for a walk in the park with her on sunday and she was fine, trotting along, good recall,..when suddenly she came to me and grabbed my arm, growling and wouldnt let go, my partner had to take her off me. She was not applying any pressure and the growling was not in any way aggressive but to an outsider it may have looked as if she was actually 'attacking' me. She does it as well after I have finished feeding her, we have a set routine for feeding - she has to lie down and wait while I prepare her food, then go through a bit of training..which she responds to very well, she is even eager to do it - but as soon as the feeding routine is over, she wont play with any of her toys, she just grabs me, as if to say ''dont ignore me, play with me NOW!'. I have tried the 'ignore' technique, the firm 'NO' and turning your back, etc..but se just ignores me, it seems to make her even more exicted and get into a biting frenzy!! When my partner's around, he just take her off me and goes off with her for a while until she has calmed down but when I am alone with her, I must admit I am stuck for ideas and a bit confused sometimes, and frustration can set in, which is soemthing I want to avoid!!
Is she testing me or trying to send me a message? Some people would say she is trying to dominate me but I do not really adhere to that school of thoughts..
Desperate for any new advice, other than the usual techniques I have mentionned above please!!!!
