It may surprise you that a number of essential vitamins and minerals actually contain an e number so this group doesn’t just include colourants and preservatives. In Europe any ingredient with an E number has had to be tested and approved for use in human food and the amount present will be restricted to levels that are known to be safe. So in some ways these tested and regulated ingredients can be safer than high levels of other natural ingredients.
Some owners are concerned about food colourants when looking for E numbers and whether these can cause allergies in their dog or affect his behaviour. Fortunately there has been no connection with allergies found to date, and whilst there are studies associating hyperactivity in children with certain food colourants, this has not been established with dogs. However, if you want to avoid these, they will be listed on the packaging of your dog’s food. This can either be in their full name for example ‘Tartrazine E102’ or under the term ‘colourants’. Here at tails.com we don’t use any artificial colourants or flavours in any of our blends, instead relying on natural flavours and beneficial ingredients, and we can offer a naturally preserved blend if required.
