I know what you mean by no blood but her whole stance is very aggressive and she just would not let go of Marcus. She has had a go at male and females, of different breeds and sizes; a lab, a cocker and a border terrier...and then Marcus.
i think I will be going to the vet tomorrow, I had thought of this but she seems well and happy otherwise......she is snuggled up to me while I type....as if butter wouldnt melt.
I have noticed since she turned one she has become calmer lying around in the house more than she used to.....settling down earlier in the evening. This is why I am surprised and upset at the recent events.
she is usually walked with my other two dogs, I do training with her a few times a week individually, just at home, she does things like pressing a button when asked in order to get a treat. Their walks are off lead in the woods and round a lake area. Her recall is great and she will sit , with the other two when asked while horses and bikes pass.
