Gigi's "baby teeth"

I was playing with Gigi this morning and a few minutes later she spit out something and was looking/playing with it. Turned out, it's one of her sharp little teeth from the lower jaw! I tried to take a closer look in her mouth, but she doesn't like people to look at her mouth. Then my sis called and said she found another one inside of her den. I called the vet and asked usually around what age do puppies replace their baby teeth with their adult. She told me 16 weeks and Gigi is 25 weeks now, so it's like 9 weeks "late". Is it normal?????????????????????? Should I be concern?????? :confused: :confused:

Puppies are like babies; they all mature differently. I wouldn't be concerned. Sylvia had a whole row of teeth that never fell out. The vet took them out when she was under anesthetic from being spayed. Worst case scenario would be Gigi has to have some removed.
