Pyometra/vaginitis

Hello vets! I’ve got a long history I would love some help with, On the 4th of June we took my 1 year old girl to the vets, she had early stages pyometra and had a full ovarian hysterectomy to treat it, surgery didn’t go great and she bled out on the table for 40 minutes, she was put on antibiotics for a week after, took her back a few days after she came off the antibiotics and she now has vaginitis, it’s been over a week since she’s been on antibiotics and the vaginitis is still there and if anything she’s just more uncomfortable and unlike herself. Took her back today as she’s uncomfortable, not herself, more swollen, high temperature(39.7 Celsius), side sitting instead of normal sitting, her belly is a little hard and her nipples are bright red. Vets put her on anti inflammatorys as well as her antibiotics and said if she’s not better by Monday (to avoid high costs over the weekend, not that it matters too much I’d rather her be healthy) to do a scan of her belly and blood tests. last night I think she stopped breathing for a few seconds, she was huffing a lot then went blank and her stomach stopped moving, a few seconds later she was ok and huffing again I’d like opinions please on what’s best for her

Hello!  As far as the treatment for the pyo goes, it sounds as though you have a direct recommendation from your vet to wait over the weekend (they must have deemed your dog's condition non urgent) and then to investigate on Monday.  It sounds as though they have given antibiotics and pain killers in case of infection and pain in the meantime.  It sounds as though, since then, an episode may have happened in which your dogs' breathing pattern may have been disrupted for a moment before continuing.  More to follow.

Having listened to people and animals as they lay asleep, I don't think it is abnormal that breathing can pause at times.  A build up of carbon dioxide / lack of Oxygen in the blood then stimulates the urge to take a breath and this may be what happened.  However, I am not your vet and carry no responsibility for making such a judgement; the correct thing to do would be to report this to your on-duty vet and chat this incident past them, so that they have all the information and so that nothing is missed.
