This is not intended to offend anyone. I love animals & do eat some meats, not store bought though (fresh free range & fresh farm animals w/ no additives) & my dad was a butcher when I was growing up so not eating meats in my house was pure sin!. I highly respect vegans but it is just something I personally can not do.
Personally I would not deprive my animals from meat. I understand dogs are omnivores but that means they also eat meat. If a lot of research is done & you can provide your animal with a balanced healthy vegan diet than go for it. I really hope that people that do feed vegan diets to their animals have a vet that specializes in that & has regular checkups & tests done to make sure the animal is in great health.
Just my 2 cents
