Hi everyone. Am in desperate need. My 6 month old seems to have totally lost the plot and has regressed into the most obnoxious creature. For some reason she has started snapping and biting at my hands and clothing for no reason. She can be sat, even licking my hand and cuddling, when suddenly out of the blue she'll just grab my hand and starts biting it. If I try to get she to stop she just stats leaping and lunging. It’s really quite disconcerting and tbh a bit frightening. This is relatively recent behaviour. She used to be so lovely. What am I doing wrong??
