Cookie decorating icing is most often Royal Icing. Here are two simple recipes for Royal Icing from my site:
Royal Icing with Meringue
4 cups confectioners' powdered sugar, sifted
3 tablespoons meringue powder
1/2 teaspoon extract (vanilla, lemon or almond)
1/2 - 3/4 cup warm water
Royal Icing with Egg Whites
2 large egg whites - to be safe, use a ¼ cup of store bought egg white instead of cracking an egg
2 teaspoons lemon juice
3 cups, confectioners' powdered sugar, sifted
Beat all the ingredients a few seconds till all is moist then beat for about 10 minutes till completely smooth. Add sugar to thicken for piping borders and water to thin for filling interiors.
Royal Icing is not a brand of icing to be purchased. It is made by using a recipe. It dries to a hard white, shiny gloss. Adding food coloring will make different colors.
Yes, it is possible to make dog-friendly royal icing for decorating treats by using ingredients that are safe for dogs, such as yogurt or carob powder instead of traditional royal icing ingredients like sugar and egg whites.

Royal icing and butter icing are completely different products. Royal icing is made with beaten egg whites (often as dry egg white powder) which break down when in contact with any fat or oil. Butter icing has a very high fat content, so the two types of icing are not compatible. If for some reason no sugar is available to make butter icing, it might be possible to reduce completely dry royal icing to a powder in a blender or food processor, then use that in place of powdered sugar for the butter icing. But that would be a very odd way of getting sugar by way of reverse engineering.
Royal icing is a hard icing that is used on cookies; when it hardens it is stiff and does not smear. Royal icing can be used on a cake but when it is being cut the pieces of it will splinter and it will be extremely tough to get a straight cut from the cake. Royal icing can be used on almost any type of food as an embellishment however it requires drying and hardening set up time.

To quickly dry royal icing, you can use a fan or a dehydrator on a low setting to speed up the process. Placing the icing in a warm, dry area can also help it dry faster.

Glycerine is a viscose, clear, colourless liquid with a slightly sweet taste. It is mainly used to soften icing. It can be added to homemade royal icing to soften the icing, making it easier to eat.
