The only thing i have against a RAW diet, is getting the combination right so your not under/over feeding and missing out on certain nutrients. Other things like it being "expensive" and messy.
Pet food manufacturers love to perpetuate such myths and fears (aka FUD). Do you buy only pellets for the children in your family, lest you miss out important nutrients and over/under feed? LOL Nutrition doesn't work like that, a first year student could tell you so.
Raw is not expensive. A 'premium' sack of crap-in-a-bag is about £35 or more. Raw feeding costs as little as £3 to £5 a month for an average sized dog. Mess? LOL I feed my dogs in their crate and/or kennel and/or on the ground outside. They chew and tear up their carcass/raw meaty bones and eat it. Then they're finished. Hardly messy.


)... Who said anything about whole chickens in Tesco? Source your whole chicken frames (with breasts removed for human consumption) from poultry wholesalers. 20kg for £3! Slaughter houses will happily fill your freezer with lamb rib racks, necks, pig trotters, heads, cattle tails etc for free or a donation in the charity box. Use your noggin and look around! 
As for the gf, trade her in. Mine skins the rabbits for the dogs without batting an eyelid lol Feeding outside is a small price to pay anyway, so meh.
