i had the exact same peoblemn with missy and kitty... i had to move out (to my grannys) and take my dogs with me... missy is mums. they were fighting for the alpha position amongst the dogs and the trainer we paid £150 could only advise us to crate one of them at all times...
try a behaviourist (or a few) by email Then consulation if you think they are good enough, i hope you get this sorted, it can get very violent... |
