In regards to eating meat

[Meerie]

[In his pediatrics textbook, Dr. Emmet L. Holt of New York City says that if two dogs were put on a leash and one fed water and the other beef tea, the dog getting the water would live longer, because beef tea does not contain any nourishment if the fat is skimmed off, but does contain urinary wastes, which poison the dog.

Only water, only beef tea? nothing else? I guess they would both die pretty soon
btw I heard that dogs can be fed vegetarian only. Monica have you tried that with your dogs?
