We've recently moved our dogs on to Viand. (you can find it by searching for viand pet food).
Phoebe our collie, is getting on a bit and we were looking for a good food for senior dogs. We ended up trying Viand and there's been a definite improvement. So we tried it with Kara too and she loved it.
The ingredients are all really natural with lots of vitamins and stuff. We're even thinking about get some for the cat too!
