Once I had a falling-out with an acquaintance about her decision to rear her puppy as a vegan. I thought she was being cruel to her puppy and wouldn't be able to raise a healthy dog. Now I'm not so sure.
And just the other day, I noticed dog food labelled as 'vegetarian'. I wondered whether it would be as good for a dog as the labelling suggested it was.
So I was most interested to see this article suggesting that dogs can, indeed thrive on a vegetarian diet.
I'm still not convinced it's possible, but this may mostly be because I don't trust manufacturers of dog food. It seems to me it's not likely that feeding a dog one type of food exclusively would be healthy. (After all, the manufacturers want us to choose their brand and feed only that.)
I'll continue to feed Penny a diet that is a mixture of commercial canned and dry food, as well as meals I cook myself, and a substantial amount of raw food - all of which is a combination of meat and vegetables or fruit.
It's all a bit of a conundrum, but so far we seem to have the right formula for feeding her.
