Well,firstly ALOT could go wrong if she IS pregnant..she is too young and also very small,right now at almost 11months old her body isnt ready to handle a pregnancy,she is still a puppy her self.You may have to expect the worst.When I was a child we had a small mutt who escaped when she came into heat for the first time and of course she came back pregnant.She had her pups 3 weeks early,they were all dead and she had to be spayed because she lost ALOT of blood

I dont want to make you feel bad but I would put a little money aside just in case because if something should go wrong etc,the vet bills wont be cheap.I dont really know what else to tell you..I would get her looked at and see what your vet thinks about this..I know my vet would remove the pups because of the mothers age and size,but each vet is different.
Hey,I could be wrong,your baby and her pups could be fine (if she IS pregnant),but its better to be safe than sorry.Also,she could just be having a flase pregnancy,one of my yorkies went through this and its also something that has to be treated.All I can recomend is that you go and see your vet as soon as possible and find out if she really is pregnant..if she is then he will tell you what to expect and how to care for your female.I hope everything turns out ok with your female.
