Why Dogs Don’t Get Dental Caries

by Barbara on October 28, 2007

in Dog Biology, Dog Treats

Dental caries are very rare in dogs (but they CAN get caries)! Though I bet you brush your teeth more often than you do your dog’s. Then why are caries that rare in our canine companions?

It’s because of a biochemical difference in our saliva. Human saliva contains an enzyme, amylase, that brakes down starch into glucose molecules. Digestion of this complex carbohydrate therefore already starts in the mouth.

This is not the case in your dog as there is no amylase in dog saliva. So starch just passes on and gets broken down later. No glucose molecules are formed in the dog’s mouth.

This beautiful mechanism is disturbed when you give your dog candy with glucose in it. Regular cookies, a bit of ice cream or just unsuitable dog treats that have glucose as one of the ingredients.

Now suppose you don’t give your dog anything with glucose, then there is still a need to regularly brush his teeth or give him the right rawhide, nylon or rubber chewing toys or safe bones. Teeth need exercise!

His gums need to stay in good condition. You want to prevent the buildup of material adhering to the teeth (plaque and tartar) as this is a environment that supports bacterial growth. It can result in foul breath and periodontitis. When you notice your dog having a bad breath you’re usually too late. Tartar (which consists of anorganic minerals) is hard and you can’t just brush it off. It needs to be removed using special instruments (that a veterinary dentist uses).

Prevention, as always, is much better (and cheaper). You can find special dog tooth paste in the pet speciality shops. It comes in different flavors.

When your dog is not too fond of getting his teeth cleaned then start very gently. Perhaps with water only in the beginning. Only rub the outside and reward him (with a glucose free dog treat or with nice words) when he cooperates. Don’t make it into a fight, start with small steps.

Safe Treats for Allergic Dogs

October 19, 2007

Allergic reactions are usually directed against proteins that are recognized by the immune system. Since this protein needs to be of a certain size to be recognized, the industry has put this knowledge to use.

When hydrolyzing proteins the parts become so small that these are too small to be recognized by the immune system. An [...]
