I'm a nervous Nellie.
My bitch delivered 8 puppies 17 hours ago. Two hours after the last puppy, I gave her a .5 ml cleanout shot of oxytocin on the advice of my veterinarian. In general is was a "clean" delivery" not a lot of blood, etc.
Usually my bitches have quite a bit of discharge at this point and in this bitch, there is virtually none.
My bitch seems relaxed, normal temp, is eating and drinking.
One girl of mine was terribly messy during whelping and for two weeks after.
The next litter with a different girl was clean as a whistle. Hardly any fluids during delivery and nothing after. Not to worry. You can always check her temp periodically to be safe but I think you're fine.
It is probably normal for her but I would ring your vet to let him know.
I've never had a girl without a discharge or with a lite discharge. Matter of fact, I worried because it continued heavily for at least 3.5 _ 4 weeks at the least. The first time, my vet checked one of the girls. There was no odor and a normal coloured discharge. It was just what I described to him, a copious discharge. In all of my girls it was copious for almost a month or longer.
I would check with your vet. My last litter had little to no discharge. When the puppies were 8 days old, in a matter of hours, the bitch's temp spiked to 106. I noticed when it was around 103 and started taking it every 15 to 30 minutes. I had to put her on meds and it took 12 hours to bring down the temp. The afterbirths were causing an infection and yes, I gave her a clean out shot too. Everybody came out fine but is was a scary 24 hours. Better to be safe than sorry.
