Hi all,
My Hungarian Vizsla bitch hasn't had a season for 14 months, prior to this she had 2 seasons, one at 11 months old and one at 21 months old. We have not experienced this with our other bitches. We have had her progesterone levels checked a month ago she was 2.9 ng/ml the week after that she was still the same and two weeks ago she was 2.4ng/ml  the vet thinks that she runs a higher base line. We have been advised to use Galastop by our referral vets but having looked this up it is to prevent phantom pregnancies and lactation, I don't understand how this would work.
Has anyone experienced this or used anything which would help to bring a bitch in season? She is kennelled with two other unspayed bitches and our stud dog.

One of our clients used galastop to bring a bitch into season. She certainly came in about 2 weeks later, but who knows whether she would have anyway?

"Inter-oestrus periods of more than 12 months are considered abnormal. This also makes it very difficult for the breeder, as every season has to be 'used' regardless of suitability of time. The long periods of anoestrus in the bitch are controlled by prolactin, and oestrus can usually be induced with prolactin antagonists such as cabergoline (Galastop). Length of treatment depends on how deep the bitch is in anoestrus, and can take from 2-6 weeks. Only around 80% of bitches will respond and the treatment can be quite costly, depending on the size of animal. However, once pro-oestrus has started it is a normal season with normal fertility."

Thank you, it might be worth a try then. My own vet is reluctant to give us Galastop long term but the referral vet thinks it will work. Raspberry leaf is used to treat the same thing so I wondered if  that might work too?
Thank you also for explaining how the Galastop works and the link to the article, it is very helpful

I think I'd be reluctant to interfere with natural hormones. Who knows what this predisposes the bitch to, in future? (Pyo?)

If she usually has a season once every year (or 11 months ish) then at 14 months, she's not really that far outside her own usual timescale. I'd just wait and give it longer, personally....She may also have had a blind heat cycle which you missed...

The referral vet wants us to give it a try to see if it helps, if not we have to have to either have tests to see if she has cysts or spay her in case of pyo, I think that you are right though and I will wait a while longer before making any further decisions, Thank you for your help

> Raspberry leaf is used to treat the same thing so I wondered if  that might work too?

I tried raspberry leaf and decided that it was a waste of time.

Ahh - I will give that one a miss then

Are you wanting to use your own dog on her? I have a bitch who had not had a season for 19 months. She then showed no signs of a season at all. No blood, no swelling that we noticed at least. She was spending days outside with one male dog and 3 other bitches, nights indoors with the same dogs.Next thing we knew she started to gain weight and she whelped four pups back in May. I had deliberately mated her daughter to the same dog and we had two good ties, but SHE did not get pregnant. One of the weirdest experiences I have had I must say. The younger bitch is 3 and has had normal seasons all her life and now I'm simply letting her live permanently with this dog.

Yes we are using our dog, they do go out together all the time so we will hope that we have the same result which you did

Well the result was okay -good mating, very nice pups, but it wasn't the mating I'd wanted.

I have brought my female Nimue into heat twice with Finilac.  My vet gave it to me.  She was due anyway, but I wanted to try to bring her into heat as soon as possible.  BOTH times, she came into heat within 5 days!  Here's a link.

Finilac is exactly the same as Galastop.

Well, whatever it is, it sure WORKED!  I was just amazed!
