One of my partner has a bitch that doesnt seem to want to come in heat. The last time she came in heat was around a year and half ago. She was bred but didn't take. Her previous heat before that she had three pups. I believe he tried cutting her weight down, and walked her but she still not coming in. I know with males I give them wheat germ oil and tribulus to help them when I plan on breeding them but what about females, what can he give her to stimulate her heat/reproductive cycles?
Almost forgot..shes been bred only a few times and had small litter each time. She's around 6-7 years old and she is a title dog.
