normally adult canines are coming in around 6 months and fully in by 6-8 months. Brachiocephalic breeds sometimes have atypical development as far as teeth go and it can take longer... though a year is pretty unusual. Deciduous teeth can complicate the normal eruption and usually should be removed if still present after 6 months.... but sometimes not always easy to tell if smaller teeth are deciduous or abnormally tiny mature teeth. Best to get an exam and see what your vet thinks.
