I have been concerned that Solomon has not lost his last 2 upper fangs, the adult cannine teeth are coming in nicely, but the baby teeth still seem fairly solid. He is 6 month old and this has not seemed to caused him any problems other than he has not eating a lot, but he is getting enough. I may try wetting his food a little and heating it in the microwave. I would like to know how soon other besenji's loose their teeth?
