Hi there, my Paisley is also 7 months old. She lost a few baby teeth about a month ago and I thought they would all fall out once they started but I was wrong. She still has quite a few baby ones in there and definately has the double teeth going on. She's been drooling really bad the past few days. At first I thought it was her eyes and now I definately know its coming from her mouth. I just called the vet to ask about this and apparently it is normal. She will be getting spayed November 1st and will have the baby teeth pulled then.
