The American Beagler Forum

Me and my runnin' buddy went in halves on this bitch and she is an excellent dog.Since her last litter she hasn't come back in heat .It has been about a year and a half to two years [I think,not quit sure.]Is there anything that we can do to [help] her come back in?Would like to have some pups out of her.

What are you feeding? Could be she is missing important nutrients. I had a fellow beagler that had this problem and had to switch feeds. He doesn't have any more problems - might want to get her Vet checked.

There are no reliable and most importantly safe hormonal regimes to bring female dogs into heat at this time. As previously posted check overall health:nutrition, intestinal parasites, heartworms, thyroid, etc.

i had a female do something similar to this she came in heat and got breed then when i weand the pups she came back in then she never came back in i don't know why.

Sometimes it works to have the bitch around other bitches in season. (worked for me)

That is often called the "Dormitory Effect" for obvious reasons...

there is a shot to give them to bring them in heat, but on the first heat cycle after the shot they won't have pups, but it helps them start their cycle again. it has worked on three old bitches i had that quit coming in heat. i forgot the name of the shot. vets don't like to give it out. it is really used to treat something else.

ECP - estradiol cypionate - will make a bitch mimic the signs of being in heat, though she makes no eggs and does not ovulate. It will often cause a bitch to develop pyometra, a serious uterine infection that nearly always results in the bitch needing to be spayed to save her life. Definitely not a recommended practice.
