I'm now considering having my bitch spayed as she's had her litters and I also have a male dog and feel this would be a sensible decision so no chance of accidents.

I'm thinking of leaving her ovaries to hopefully not have the affect on her coat and potential weight gain.  Thoughts/experiences please

Also, would a laproscopic spay be your preferred option?

My brooke had a oss laproscopic spay. Recovery was very quick and I assume all was done properly as we have had no problems with pyo .
Her coat has still gone well and truly woolly just as well we stopped showing as she hardly looks like a flat coat most of the time. Weight gain is hard to say because I keep a very stricked eye on her weight and she has always been very foody
Would u do it again ? Apart from recovery I haven't found any difference .
If u are on fb there is an os group

There is a group on facebook for ovary sparing spays, if you're on there.  Very useful.  The main concern in your situation would be that she'd still have seasons, but with her uterus and cervix removed, if your male were to get to her and mate he could do her damage.  She'd still be willing when ovulating but less room down there to maneuvre, so to speak!

If you leave her ovaries she will still come in season and be attractive to males as usual. The only difference is that there would be no discharge and she would be highly unlikely to get pregnant if mated - extopic pregnancy is theoretically possible. You would still be sensible to keep her and your male separated when she was in season toprevent either of them getting injured when they mated.

I'd get her 'normally' spayed.  That way she'll not come into season and there'd be no risk of him getting to her, or having to separate them.  To be honest, my bitches didn't have a significant coat change (unlike the odd male I had to have castrated for medical need) and if you keep an eye on her food intake/weight, that shouldn't be a major problem.
