Actually, that is not correct. It is a fallacy and one used to support raw and barf feeding.
Anne, I am always willing to learn. The connection between skin problems & dry food came from my own experiences with dogs over the past 40 years. If you know of studies that show this to be a fallacy, I'd be interested to read them.
I'm not sure her allergies issues are from a food allergy as such - I guess just looking for some food items that will help. she breaks out in hives when we take her to certain parks and definitely right after the cut the grass. So the whole diet change thing is mostly related to her weight loss, with some tips on foods that help control allergies and itchy skin.
She does get heaps of exercise. 2 x 30 min (at least) walks per day, most of which are spent at the dog park running and playing with other dogs or with her ball.
Anyway thanks heaps everyone for your advice. I think what we'll end up doing is trying a different kind of mince, cutting back the carbs and filling with veg and see how we go. We've tried supplementing with sardines before and it softened her stools a bit too much so we try to keep away from that. I'll try mixing it in with her food, I'm also going to try adding some linseed and apple cidar vinegar because I've heard both of those things help heaps too. I'll keep you all posted on how it's going!
As a side note - a really good short term relief therapy we tried the other day, after a major hive flare up (they cut the grass at the dog park!) - we bathed her her cool water and colloidal oatmeal for about 20 minutes and that worked wonders. She was NOT a happy camper about sitting in a tub full of cereal but stopped itching and the hives swelling went down and red paws faded back to pink so I highly recommend that treatment! We've also used the Rufus and Coco "Itch Relief" natural shampoo on her as well which has helped when she's really itchy.
Oh the things we do for our fur babies eh guys?
