It could be many things. Plants, certain human foods, viruses, and poisonings are the most common things that make dogs sick.
Dogs eat grass in order for them to throw up things that are making sick, such as what cats do with furballs. They do this naturally to get rid of whats making them feel sick, by eating grass.

They could get sick. How sick would depend upon how many and what kind of microbes and/or toxins were in the meat that they consumed.

No you can't get sick from touching outside snails.
Yes, dogs can get sick at any age, even if they are young and old.
Though some breeds are hardier than others, I would never recommend to someone to keep their dog as an outside dog. Outside dogs are rarely well socialized and can suffer health problems from the exposure to the elements. A sick, unsocialized dog can pose a threat to your family and your neighbors and is a liability.
