Hi there, I'm new. Looking for the best mid-priced dry food for my 7 year old rehomed Border Terrier who has anal gland issues. I moved her from Wainwrights to Royal Canin Midi (up to 10kg) which seems to have sorted the glands out, but has made her put on weight as well as her recent spaying, I think. I'm wondering if she needs to be on a small dog Royal Canin as she was under 10kg before or their lite variety? Or maybe Royal Canin is just not right for her. She's moderately active.
