Research by UNE scientist shows dogs
thrive as vegetarians
21 Dec, 2009
Wendy Brown is at the centre of groundbreaking international research that has
found that dogs can thrive on a meat-free diet.
Dr Brown was part of a
team of scientists who monitored the health and performance of Siberian huskies
over a 10-week sled-racing season.
They concluded that hard-working dogs
can perform just as well on a meat-free diet as they do on a meat-rich diet.
Their results, published earlier this year in the British Journal of
Nutrition (Vol 102, pp 1318-1323), add to the evidence that dogs fed an
exclusively vegetarian diet can be just as healthy and happy as their
Dr Brown, the canine nutritionist from the
University of New England who led the husky trial, is confident that dogs can
thrive on a meat-free diet.
She warns dog owners, however, that preparing
an adequate vegetarian diet for a dog is more difficult and time-consuming than
they might think.
Dr Brown has concerns, too, about some of the
vegetarian dog foods that are becoming commercially available in growing
Many of these, she said, are untested.
manufacturing and buying vegetarian and vegan pet foods are often against
testing, believing that even feeding trials are cruel,' she said.
feeding trials can be done in a friendly way. For my own trials, I borrow
people's pet dogs - some of them show dogs - and they are always well cared for.
People visiting my kennels comment on how happy the dogs look. And they are.
'When I feed my own dogs, I want to know that what they're eating is
'As dogs belong to the order Carnivora, it's
often assumed that they are exclusively carnivorous, but in fact they are
omnivores, belonging to the same superfamily within the Carnivora as the
bamboo-eating giant panda and the omnivorous bear.'
In a paper presented
at the University of New England during the international conference Recent
Advances in Animal Nutrition 2009 and published in the conference proceedings,
Dr Brown addresses the common argument that vegetarians should not impose their
own values on their pets.
'A similar argument is often raised when human
parents impose their religious or moral beliefs on their children, particularly
when the belief system differs from that of the ethnic majority or predominant
culture,' the paper says.
'In either case, it would be wise to assess the
situation without prejudice.'
In the case of dogs, Dr Brown says,
vegetarianism should be assessed purely from a nutritional perspective - i.e.,
whether the diet meets the dog's nutritional needs, maintains the dog's health,
and is sufficiently enjoyable for the dog to eat enough of it.
has shown that vegetarian diets can meet these requirements, but that the
preparation of a home-made vegetarian diet for a dog can be an exacting and
