I would guess the unspayed one is getting ready to come into heat. A couple of weeks before a female comes into heat at my house, the fights between the girls usually start. The only way to stop it is to have her spayed and it's possible that they may not like each other for life. Things may settle down after her heat is past but will flare up again with her next heat. I have not had a lot of luck with this because I don't have a kennel or keep my dogs in cages. I'll be interested to see what others say. |
