asking for thoughts on dog food.

[mopinko]

so, my bully dog is losing hair on her sides. weird pattern, same on both sides. no sign of skin irritation, just hair loss. took her to the vet. nothing wrong they cd find. recommended a fish oil supplement, but i’m a bit skeptical. vets seem to rec a lot of supplements/alt treatments that have not been proven, or in some cases disproven. like chondroitin supplements which have never been proven to repair cartilage.

i’m thinking i cd afford a higher quality dog food for her. maybe a fish based 1. i dont think the whole hog ppl food is worth the money. but curious is anyone has thoughts on what brands r worth the money.
i’ve fed purina to most of my dogs on the rec of my long time vet. many vets rec them, as they do have the strongest research arm. my dogs have always lived to a ripe old age.
currently feeding a brand called optim, which is what the breeder fed.

so, just wondering what folks here think.
