My Daisy has started her first Heat season (lady days)
She is very aggresive to my 18 yr old female ACTUALLY very mean.. attack mode..
And the other day My 1yr old female spent the nite with my granddaughter and when she came home Daisy Attacked her too..
I have had to remove Daisy from the room.
Why? Is it because of her lady days.. She has always been so playful and loveing...I am worried I might have to give her up..

Do dogs PMS too
