Hi, does anyone know at about what age a female dachsund should be going into heat or bleeding? I have a 2 yr old purebred female dachsund who is from a long line of quality prize winning show dogs and as of yet I cannot say for sure that she has ever started bleeding or been in heat. She is a miniature long haired dachsund, I am not sure if that would make a difference to her cycle or not. If anyone knows the answer pleae help me out.
