How do I change my dog’s food?

If you are going to switch your dog’s food because of a sensitive stomach, or a stinky behind, then it is best to do this carefully. 

It is vital that you change your dog’s food very gradually to avoid further digestive issues or stomach problems. To do this, you will have to transition your dog over onto the new dog food.

You will need to gradually introduce a little of the new food in combination with their old food until they are weaned onto the new formula completely. 

This can be done over a period of seven days, where you add more and more of the new food into the dog’s system. Start on days one and two with the majority of the food they are used to, mixed in with a little of the new food.

On the third and fourth days, try to do a 50/50 blend of the new and old food, gradually adding more of the new food on days five and six. 

By the end of the week, you can start giving whole scoops of the new food, as long as there are no symptoms of a stomach upset, or digestive problems.

Before making any drastic changes to your dog’s diet, you should always consult with your dog’s veterinarian before starting.

Tell the veterinarian about any issues or allergies your dog may have as they may have some suggestions for the best foods for them.
