shit Damon I'm really sorry to hear that your dog is needing more surgery, hopefully she will not need any more after this,
What brand of dog food is it that you are feeding them, and is it readily available in most pet food stores.
We were feeding our dogs
Innova Puppy Food until they were 8 or 9 months old and then switched to the adult
Innova Evo that they are still on today. The food is an organic all natural human grade no grain dry food.They are almost 3 now in great shape and have never had any health issues. their coats are soft and shinny, one being so soft that it resembles rabbit fur.
I know how stressfull surgery can be for you and your dog and I hope all goes well with that
