My baby girl (2 1/2 months) has a dry nose sometimes. I've had her for almost a week and I've noticed this maybe 3 times. She saw the vet 2 days after I bought her (from a pet store

) and got her 2nd shots. The vet said she was healthy. Is this normal? What does it mean? Also at other times I notice her nose is very runny, much more often than it is dry. She also scratches at her ears quite a bit. I'll call the vet tomorrow, I've never owned a doggie before so I worry a lot about her, Thanks for the help.
