Really?
You don’t know by now that these folks are going to tell you that Victor does not meet the WSAVA guidelines.
Just a suggestion, make a list of all the grain-inclusive dog foods that appeal to you.
Call your veterinary clinic and leave a message for your veterinarian to call you back when he has a minute.
Ask his professional opinion as to which would be the best product for your dogs.
Odds are that he will advise you to buy in small bags (one by one, none of this rotating crap) and through trial and error see what one the dogs do best on.
After all, he is the veterinary healthcare professional that has examined your dogs and knows them best đ
PS: I have never used Victor, never heard of it till I came on this forum, maybe it is only available in certain parts of the country.
