Layla gets her teeth brushed daily- i started when she was about 6 months old- i use an infant toothbrush and doggy toothpaste- she hates every minute of it but tolerates it- I woudl start slowly- let her lick the toothbrush and get used to it. When i brush Layla's teeth I lay her on her back on my lap and pull her "cheek" out and brush as long as she will let me
with dogs you do not have to worry about the in- side of their teeth- just the outside- no idea why but that's what i was told
