Yes, a dog over 50 pounds is considered by many to be a "large dog." My dog is 57 pounds and I feed her large dog food. She is very healthy and muscular.
1 pound of food
one cup of food a day
feed you dog some treats or dog food in a bowl at your house
Unless you are planning on cooking it, i wouldn't feed a dog raw meat.
How much to feed a dog is based on their breed and weight. Most brands of dog food have a recommended amount chart of their food on the back.
If usually says on the package, but asking your vet how much dog food to give your dog would be a good idea.
30
maybe 2 pounds of food
6 to 9 pounds
The one thing is don't feed your dog too much human food. It will get them aggresive!
