I agree that 9 weeks is a bit young for a Yorkie to be separated from his mom and litter mates. At 9 weeks, my puppies do sleep a lot but they also have very active periods where they play like crazy and then they crash and sleep for a while. Is your baby having active periods and then getting sleepy or is he sleepy all the time? I do agree that you should get a vet check up anyways. This is about the age when I start their first shots too.... |
