The study shows that about 163 million cats and dogs in the United States are eating up 33% of animal-derived calories that humans do.
That’s some carbon "paw print" for our furry friends.
But the protein might be necessary for happy, healthy pets.
Dog trainer Jennifer Gray has rehabilitated hundreds of dogs and has worked with Cesar Milan from the TV show "Dog Whisperer" in her nearly 30 years of animal service.
She says she’s seen a correlation between “Vegan diets- I’ve seen dogs on them,” says Gray. “They don’t have as much muscle tone, they aren’t as alert and they definitely don’t learn as quickly.”
To avoid breaking the bank and keeping pets healthy, Gray recommends mixing high-protein kibble with raw foods.
To help reduce your pet’s carbon "paw print", choose chicken instead of beef, pork and lamb which have the greatest ecological impact.
