Every dog is different and I am always happy to meet with you and your dogs to discuss specific cases/needs but as a general rule of thumb I recommend feeding your dog approximately 2-3% of their body weight daily
2%: Inactive/older dogs or dogs that may need to loose a bit of weight
2.5%: Normal activity/healthy
3%: Very active, outdoor dogs
If you are mixing with Kibble, I would recommend a high quality kibble with no grain and make sure it's Australian owned and made!
