Im glad that the pup was okay.
Because your Bella had two of her shots it is unlikley that she could have gotten it, here in England the pups only have 2 shots (at 8 and 12 weeks) I know they have more then 2 in the USA, but it will still leave it unlikley that she would catch it.
Thats not 100% though because Im sure more experienced breeders/owners will correct me if Im wrong
Glad both pups are doing fine.
