Thanks Matt,
Glad I could help. I prefer to see soy as a protein source in a veg. diet as it has a decent AA profile. I think (???) Nature’s Recipe has been through feeding trials and they have a canned version which is a little higher in protein than most dry veg. diets if you carry that brand.
One of the concerns with vegetarian diets is getting enough sulfur containing AA into the dog. If the diet is marginal in those AA and the dog’s energy intake to maintain a good body score is on the low end, the dog may not be consuming enough food to meet it’s AA needs. ( Newfoundlands have much lower energy requirements than other breeds which is why I think they were the ones to suffer from the effects of the aforementioned Lamb and Rice diet.)
Kind Regards
