Yep,. in a sort of glass tube with a bung in the end, I have a recollection that we just dissolved them in ....... no, "water for injection".

I wonder how often persistent lactation occurs, 'cos I think we avoided spaying in lactation for that reason??

Probably not but owners were concerned and one of younger vets had mentioned cancer !

Themalon- that was a drug of long ago memories. Was that the tablets that were crushed and dissolved in saline ?

Responded partially to galastop , then came up again , then both caudal mammary glands became swollen with a grey-white material on needle aspirate. So she has run up a total of six visits , a needle aspirate, culture and sensitivity tests and now several bottles of galastop. I tend to leave them till at least three months after the end of a season .[/quote]

Is it causing any problem for the bitch?

I have recently treated a bitch that was neutered in the last stages of a pseudo pregnancy . Just a small amount of milky discharge that the clinician thought would be insignificant. Four weeks post spay she developed swelling in one caudal mammary gland. Responded partially to galastop , then came up again , then both caudal mammary glands became swollen with a grey-white material on needle aspirate. So she has run up a total of six visits , a needle aspirate, culture and sensitivity tests and now several bottles of galastop.

Have you tried looking on EntrezPubMed.com? That is my go-to website when looking for evidence containing all published reseach in the medical and veterinary fields? I tried and found reference to pseudopregnancy in rats but not to dogs yt. A lot of references to links with diabetes but over to you to look for more as per you need...

It is a free site. Here is the search page:

PubMed (nih.gov)

HTH?

This is exactly the sort of info. that would have been hard to find, but so helpful, when I was bumbling around way back in the days of Themalon and thio!

ditto

I should have said - in the ones I've seen, the pseudopregnancy then stopped after spaying!

I find speying at the time of c-section easier and quicker than closing the uterus. In fact one of my regular practices charges slightly less for concurrent speying than not at c-section

Inducing pseudopregnancy by spaying in progesterone phase - should I be worried? (vetsurgeon.org)

I think there may be a division to be made between

1) during lactation at time of cesarean in pregnant bitch (I can't see a problem other than seems to require a lot of clamps and may prolong the GA in a potentially compromised bitch; I do very few cesareans, so can't comment from experience)

2) during the progesterone phase in the non-pregnant bitch.(might cause more obvious signs of lactation than might otherwise have seen - treat with cabergoline if does and deemed necessary)

3) during oestrus - might be more likely to leave a bit of ovarian tissue behind

4) anestrus (either pre-pubertally, or between cycles with pros and cons of each to be discussed in a different thread!) - surely the best general rule all things being equal, but not a reason to avoid spaying at other times if reason to.

I will spay a bitch literally at any point in the cycle and I've experienced no difference. Done lots (dozens) accidentally mated and zero problems.

I love this question and was only bringing it up yet again last week and have asked the question on this forum a few years ago

Facts (I'm sounding like a dinovet)

1) Vets spay bitches loaded with milk at the same time as caesarians

2) I have never seen a persistently lactating bitch

I feel really sorry for this poor clients dealing with bitches who constantly have false pregnancies because no-one will spay them, because by the time they are finished they are in season again and the whole cycle repeats.

Mair Tyler — Thu, 04 Mar 2021 22:36:52 GMT

That's my feeling about it too but many vets will not spay a bitch in false pregnancy because of the apparent risk of a chronic pp not responsive to cabergoline.

Bitches can have a spur of prolactine if spayed in the luteal phase but I never seen or heard of a bitch in persistent lactation post spay. Worst case scenario is a transient lactation that can be controlled with cabergoline.
