So, everything appears to be back to normal with the pooch. There was a bit more bleeding on Friday night, through to Saturday night. And by a bit, I mean drops, which is entirely consistent with her un-spayed physiology.
We’re uncertain which orifice the initial blood came from. She’s getting older and the output from her seasonal feminine cycle has lowered to usually just mere drops in last couple of years. Is it possible that this last round was the result of some form of doggy menopause?
Or, perhaps the bleeding came with the diarrhea? We really don’t know, but she slept for a good few hours on Friday night, sequestered in the laundry room, and then woke us up to complain about the loneliness. My wife’s been off work so far this week and the dog apparently will not leave her side.
To sum thinks up, everything seems back to normal now including appetite, but she does seem a bit more cuddly. I have not been around to examine how any of her poop has looked since, but she seems to be fine now.
Bleeding from stones comes and goes, just FYI. I would (especially!! because she’s a Bichon) at least have them run an UA on her. If she is “in heat” she would be swollen in her private area, so if that is not true, there is probably another explanation for the bleeding. Not a vet, just worked for them forever :).
Dogs don’t get menopause… IF she has completely stopped cycling (gone through years you don’t notice any “heat”), only to return now with blood and diarrhea, that is unusual.
Perhaps she ate something she shouldn’t have. Any change in diet, any indiscretion, anything she could get her muzzle on.
I didn’t ask whether or not I should take the dog to the vet. I was looking for possible causes for the event. She’s calmed down now and all seems well.
OPs have already told you, but dogs don’t have menopause, and their fertility cycle is vastly different than a human’s. Their uterus, like ours, will build up a thick, blood rich lining before ovulation. But unlike humans, this lining is never shed - and it is therefore ripe for infection from outside sources. Bleeding from the vagina in any quantity except a few drops is not normal in canines.
For some reason, the likelihood of pyometra increases with age. You dog will remain fertile and go through heat cycles well into old age, with an increased chance of this happening again.
I think you’re being very irresponsible not to take her to the vet. It seems she has at least partially recovered from this episode, but it could still become more serious. Pyometra hurts quite a bit, and it can kill your dog.
I don’t think that the OP is going to get much more factual information about his dog’s condition without going to the vet, so I’m going to go ahead and close this.
