Re homed a cocker spaniel on Saturday. She came with purina but will not even look at it. We're on day 3 and she's not eaten a thing. I was preparing my other dogs raw this morning and she seemed keen to try it so I gave her a taste and she gobbled it up. She's done one pop since she's been here and it looked runny with worms in it so I've ordered her a wormer which is coming today. Should I put her on a raw diet? Trouble is I don't know if she's allergic to certain meats. My other dog can't eat poultry so there's only fish, pork, tripe and beef here.
