Question
I just adopted an abandoned black lab puppy. I want to know how old she is so that I can give her the proper flea treatment (most are not suitable for puppies under 12 weeks old). How can I tell how old she is? Is there an average weight ratio or tooth size? The lady I adopted her from guessed 8-10 weeks and she's about 20 lbs.

Answer
The 20 pounds suggests more than 8-10 weeks. Between 8-10 weeks, the teeth stay about the same but the jaw lengthens opening up gaps between the teeth which the adult teeth soon start filling in.

The best thing would be a vet check. Unless you know it recently had shots, it needs a round of them. If you have mosquitoes, it needs heartworm remedy. The vets have the best flea stuff. I know the Revolution I use is OK for puppies over 6 weeks.
