Has a bitch tci'd yesterday, brought her home and her sister who is coming off heat went crazy....
She was sniffing and tried to hump her... they were in my bedroom.... I separated them
She then proceed to bark.... When she calmed down a bit... brought her back in for a nap... she again tried to rub her behind against the other one... Is this normal?

When they are "hormonal", nothing's out of bounds. LOLOL

Totally.
