My jill has just had her first (and last) litter 3 weeks ago, she had 8 healthy kits and theyre all doing well. She was never protective over them and i have handled them daily from 2 weeks old, and she was more than happy for me to do so. However 3 days ago, my jill launched at me and latched onto my chin, and has been showing serious aggression towards me since. Her diet didnt change, no one else disturbed her, i didnt take the kits out of her sight and didnt hold them for more than a minute each, nothing had changed. I went in there and she launched at me before i even touched them that day. I am wandering if it is hormone issues, she has a very thin coat particuarly towards the back end but i thought it would be because of molting, and she has lost a bit of weight too but shes just had kits so id expect that. I work at a vets and will take her if it does not improve but i am not keen on the idea of taking her away from them even for a couple minutes when they are so young. If anyone has any advice it would be really appreciated. Kind regards.
