I read somewhere on the forum that there was a litter of 10 puppies born recently. This is going to sound like a weird question but I just have to ask – How many spots are there supposed to be at the milk bar on the mama and what happens if there are more puppies than spots? The other day when I was petting my girl I noticed that she only has nine....
I was thinking there are 8-10, but that it doesn't usually present an issue as litters are normally about 4 or 5. In the wild, when there aren't enough spots the weakest one(s) tend to be malnourished and often don't survive too long. With pets, it's a lot easier to regulate that everyone gets a share, with some intervention, there isn't an issue anymore.
Rally has 8 but only 7 get milk. Rio looks like she will be like her mom 6 should definitely be functional and I think the 7th too but there is 1 I don't think will get milk. Neither Rally or Rio are symmetrical in their nipple placement.
Sophie has 8 perfectly symetrical nipples that all look like the will get milk. She gets milk in the rear ones during her false pregnancies already.
My Fatia has 9… one is inverted and thought to be not usable... however, when we bred her, she did get milk in that one and they were able to nurse... of course it was only a litter of 4, so it was not really needed.... even if they have 10 nipples and all are "working"... after the first couple of days, need to supplement the pups because the bitch really can't supply for that many without really dragging herself down to skin and bones...... I know that many people that have multi litters, if one litter is small, they will try and change off pups to the bitch with a lower number of pups...
It took me a little while to realize that dogs weren't always symmetrical. I thought for the first day or so after Medjai's hernia repair/neuter, that they messed up and shaved one off. It wasn't a big issue because he won't be needing them for anything, but it was a little shock, because I hadn't noticed it before.
