I rescued my Chi (Sadie) from a very bad home.. so I haven't had her since she was a pup. She has been with me for about a year now and is in her second heat (since she has been with me) when she came to me she was just coming out of heat. I am getting her spayed after this cycle as my vet has advised me to do. But what I'm wondering is why my Chi doesn't bleed? Is it possible that she doesn't bleed? Her previous owner told me she hasn't bled during... and she is just showing signs now.. This is her first full heat with me so I'm wondering more what to expect?
