Please don't allow the dog to be around at this time or any other cats, she needs to be left with the babies, until the kittens have had first vaccinations. Speak to your vet about a good worming schedule for Mom and babies, please don't use over-the-counter wormers, they can be dangerous. Weighing the kittens on a daily basis is important, I go off grams for the first few weeks, making sure they gain at least 10 grams a day or more, but if you are using ounces, then know 16 ounces are in a lb, to help keep an idea of weight gain or loss. Keep Mom and babies warm and comfortable inside a room such as your bedroom or bathroom.
It is my opinion Ragdolls should have only certain vaccines, but this is something you should speak with your vet about, however, I would recommend NOT giving FIP or Felv. Also, I wouldn't give rabies until at least the kittens are 4 months of age. We stick with a killed FVRCP only, but some vets do use the ML.
You may decide you want to contact CFA for a mentor, if you have decided to become a Ragdoll breeder, I believe they have a mentorship, or ask someone with years of experience to be your mentor in your area. Many of us began with a mentor, the learning doesn't seem to end, it just keeps going and going, and there may be new information about the Ragdoll breed, that you are not aware of, that becoming more informed with the cat registries and breed clubs and health lists may help you stay more aware of standard revises or health news.
