Anyone on here a decent dog trainer? I'm kind of at my wits end with my rat (chaweenie)... he's fine with me and my husband, he's fine with other people when I'm around... but we went out of town this last weekend and had a friend (that he knows and likes) go feed them one day and it turned into a bloodbath... he bit her thumb pretty badly, it's healing and doesn't look like it's infected (impressive since he had a mouth full of raw chicken right before he bit her...) and she's not mad, but I certainly don't want him doing that again... She tried to take his food away from him is what started it, not an excuse, but it is what set him off.
