Can any one tell me how offen a daschund female goes into heat or season, I got a female in dec.2007 the last owner says she was in heat in August. Its now march 2008 she still hasn't not gone onto heat. I have a male dauschund which is five years old and the female is two years old I would like to breed them one time for the pups .not to sale pups but to get to some of my family free. What I need to know is how offen should the female be in heat ?
