I have no poblem with vegetarian diets for dogs (that are nutritionally balanced of course). I had a dog that couldn’t breakdown animal proteins. (If there were enzymes available for it then I would’ve given him that instead). He was a vegetarian. But still got his protein from eggs. Which is a food that has the highest biological value. Eventually it was realized that a lot of dogs were having difficulty with the most common meats in dog foods because of the sources & inbreeding of the animals, etc. He did fine with kangaroo & rabbit.
Anyway, vegetarian and vegan diet are NOT the same thing. Dogs have been close companions of humans for 45,000 yrs. You bet they have evolved. They are more omnivorous than ever and actually do best on a diet of plants, grains and MEATS. While they can adapt to a WELL-BALANCED vegan diet, they do best with a diet of animal fats & proteins.
Vegetarian & vegan diets require adding synthetic amino acids. Dogs cannot produce these very important elements themselves. Make sure none of that is sourced from China.
If you go to certain parts of the world you will see lots of dogs on the streets surviving on whatever they find. While that shows they can adapt, I wouldn’t exactly say they are thriving.
As for the dogs that have lived well into their 20s on vegan diets I don’t believe they aren’t getting appropriate proteins somewhere. I would bet they eat other animals. Mice, birds, whatever they hunt unknowingly to their people.
The cattle dog you mentioned admittedly wasn’t vegetarian. But I also have to say that I doubt Guiness followed that dog through its whole life. Who’s to say it was 29? Were they able to prove it by means other than a birth certificate? I couldn’t find any other means used to prove the ages of the oldest dogs. It appears they were (assuming their ages were real) the exceptions. Miracles really.
We all want our dogs to live as long as us with the best quality of life. Sometimes that means not anthropromorphizing them, doing/feeding things that are disgusting to us, but necessary to them. Or making difficult choices that will break our hearts, but will relieve them of pain. They are dogs. They are not humans. We have a great responsibility & are privileged to provide them with everything they depend on.
I only want what is best for anyone’s animals.
It is incredibly selfish to insist that your dog should be vegan because you are. Even if you supplement appropriately it isn’t the same as getting nutrients from the right food source. “Let your food be your medicine.”
I understand some dogs need to be vegetarians for health reasons. I have been there when other options weren’t available until later in his life. As soon as I discovered other choices I tried them. Because he was a dog. I didn’t love feeding him kangaroo or rabbit (we have rabbit pets. His best friend was a rabbit.) But he didn’t know he was eating cute animals. He only knew & cared that he was eating and not feeling bad afterward.
I should mention that I have only ever had GSDs my entire life. None of them that I raised developed arthritis or hd. Others I have adopted/fostered improved almost instantly once given an appropriate diet & exercise for that individual dog. Right now I have 3 dogs and 5 different foods because all of them need different things at the moment.
My point is just do what is best for the dog. Don’t push your beliefs on them. They don’t care. Feed them meat products. Even if it’s just eggs and raw goat milk. But make sure they get a balanced diet. If they live to be 20+ that’s awesome if they are healthy, happy, pain-free. If they live to be a happy & loved 10 year old without any suffering, then you’ve done your job.
Their time with us flies by. Enjoy them fully. Love them completely.
