Well this isn't normal! I'm wondering if you are sure that Hazel did lose her baby incisors. It does happen that the baby teeth don't always fall out, and the adult teeth grow in behind them. This is something that needs to be checked out by a vet, and if she has retained her baby teeth, then they will need to be removed to make room for her adult teeth. Give her vet a call to make an appointment for her. Best of luck, I hope this helps.

    Molly should have lost her puppy teeth by now, especially if there are two adult teeth growing in behind two puppy teeth. This means that these two teeth are retained and they will need to be removed in order for her adult teeth to grow in properly. Not having these retained puppy teeth removed with have adverse effects on her bite, it is best to have them removed.

    At nearly 7 months of age, all of the baby teeth should have fallen out. If there are retained baby teeth they will need to be removed, or the mouth will have considerable crowding - especially in a Pug. This is relatively simple to do, and we often do this while they are under anesthesia to be spayed. Definitely, it should be dealt with very soon.
