You have to give them rawhide to bite or even raw bones.. You can try going to my vet in Bandar Puteri. Dr Edmund. I think it should cost less than RM300. Lucky my old lady doesn't have this.. She's perfectly healthy for her age suprisingly.. Took her to jungle trekking with me that day and she got more stamina than me and pull me some more..
once the teeth are scaled , you should start maintaining it by brushing if u can everyday, feed food that will make the dog use the teeth, helps, but it won't clean all the teeth all round, plus old dogs are also tired to chew too much...
use good toothpaste like Orozyme or CET,
