Hi I'm new to this group.
My bitch had her 3rd mating 5 days ago. We did this by AI. However today she has peed 3 times in house which is very unlike her.
She has no discharge, not lethargic and is not showing any other signs of pyometra or a uti.
She stopped bleeding completely yesterday. I've not had this problem before and her last season she didn't mess in house.

Any advice would be helpful. Obviously if she carries on I will take her to the vets.

Not to fuss but if this is unusual for her, I think I'd collect some of her urine and get your vet to run a urinalysis.   It is possible she's picked up some infection which if she is pregnant, needs to be cleared up.   To avoid any further risk of infection, it might be a good idea to just take the urine in, unless you vet says otherwise.

Thanks for the reply.

She has stopped now. No accidents over night and no behaviour changes.

I'm guessing it was something to do with coming out of season but I'm keeping a close eye on her.
