Celery – is great for dogs and can help maintain fresher breath. Celery can improve heart health and lower blood pressure and is believed to help fight cancer. It has Vitamins A, B1, B2, B3, B6, B9, C, E and K. Calcium, Iron, Magnesium, Phosphorus, Potassium, Sodium and Zinc are all present too.
Silverbeet or Chard- is a great addition to natural diets for dogs. It does contain oxalic acid but again, huge amounts of Silverbeet would have to be fed to get to toxic levels and is very safe in a balanced, wholefood diet.
