Choose a day of the week and trim their nails regularly, even if it's in tiny increments. Same thing if the dog requires brushing or other grooming, set a schedule and stick to it. Again this will be harder with an older dog vs a puppy, but it will help so much to get the dog used to it.
This! Get them used to getting their nails filed/trimmed and teeth brushed so you don't have to rely on professionals to do this for lots of $$$.
