Let's just put it this way, animals can't live without bacteria. I know that sounds crazy, but there are different kinds of bacteria. The kind that you and I think about a lot are hetatroph bacteria. They cause us to get sick. Autotroph bacteria on the other hand live in you and me inside our intestines. They also live in animals. If we and they didn't have them, we'd die. Hope this helps!
Yes. There are bacteria inside the digestive tract of a cow and other grazing animals that helps to digest fibrous plant material such as cellulose.

Bacteria is everywhere so yes, it's on animals, in dirt, in the air, on and in food, in and on our bodies and is most often beneficial or benign.
Some bacteria are beneficial to their hosts.
Animals that chew their cud (aka, 'ruminate') are called ruminants. This is beneficial to these animals because they have bacteria in their stomachs that digest the various plant materials the ruminant eats. To help the bacteria digest the plants, the ruminant brings up a wad of plant material (called the cud) and chews it thoroughly to mechanically break down the tough structural fibers of the plant. The ruminant then reswallows the cud, the bacteria digest the plant and both the bacteria and the cow get their necessary nutrients from the plant.

Some bacteria are beneficial to humans, and some bacteria are harmful to humans.
The bacteria in the intestines is beneficial. Acidophillus bacteria as in Yogurt is also beneficial . Lactobacillus is used commercially in dairy industry widely. Escherichia coli, an intestinal bacteria helps in digestion and absorption of food . Staphylococcus aurous, a bacteria present on our skin, aids it in immunity. It prevents the invasion of foreign microorganisms by releasing certain toxins.
