It is recommended that you get a pair of Fiskar brand kindergarten scissors with the blunt end for cutting eyebrows, you still have to be careful but at least you do not have a pointed end. Again, you can use the blunt end scissors for this if you are worried about stabbing the dog if it moves its foot. Long hair between the toes on the top of the foot may be coaxed up with your fingers and trimmed to also neaten the foot. This can also be done with the hair around the foot and the long hocks on the rear feet. Trimming of the excess hair should be done every 3-4 weeks.
Dental care is very important for dogs.
The problem is not cavities, dogs get very few. The problem is plaque, the stuff which forms on teeth at the gum line and which gets progressively thicker if not cleaned off. Plaque is easy to see. Hold your dog's lip back and look at the top of its molars. You'll see a dark, uneven line of stuff where the teeth emerge from the gums.
