So you've taken the plunge and decided to switch your dog to a raw food diet.

There are various theories about how to transition your dog to a raw diet and the important thing to realise is that isn't a 'one size fits all' approach.

Ultimately you have two methods available to change your dog's diet from wet or dry food to a raw diet - Immediate or Gradual. Let's explore each option in turn so you can decide which suits you and your dog best.

1. Immediate Transition

The Cold Turkey Approach

Firstly, let's look at the immediate approach.

An immediate transition is perfect for puppies and young dogs with a young healthy digestive system. Most dogs transitioning on to a raw diet find that they have very few short-term side effects.

Many experts advocate a straight and immediate swap of foods. As feeding both dry and raw foods together can put unnecessary strain on your dog’s digestive system, an immediate swap can be the simplest solution.

But it's worth keep a diary of any noticeable differences including weight changes, changes in stools, bad breath and possibly some vomiting. Persevere as it may take a few days for your dog to adjust to their new diet. Of course, contact your vet if you are concerned.

2. Gradual Transition

Slow and steady wins the race

The second option is to transition gradually over a period of time. The gradual transition is perfect for older dogs who have been fed commercial dry foods their whole lives. Their age may make them more susceptible to dietary changes.

This method can take anything from a few days to 2 weeks.

Start by calculating your dog's daily raw food amount using a website feeding calculator.

For the first week, offer your dog 50% of their existing food and 50% of their new raw food in separate meals. Don’t mix the raw and dry foods together as they are digested differently. Dry dog food can take up to 16 hours to digest while raw dog food only takes 4-6 hours.

Feeding both together should be avoided. So feed the 50% existing food and 50% new raw food meals as far apart as possible (ideally 12 hours apart), to help digestion. Maybe one for breakfast and one for tea.

If after a few days your dog's digestive system is happy with the raw food, gradually increase the percentage of raw food. After a week you should be feeding 100% raw for each meal but the transition period can be extended if you feel you need to.

3. Changes to Expect

Dogs drink less

Dogs are able to absorb far more moisture from a raw diet than a dried kibble diet so you may well notice that your dog drinks less. This is normal just ensure that you continue to provide fresh water at all times.

Dogs poop less

As raw dog food is more digestible there is minimal waste, so less poos. Also they can often be smaller so much less scooping the poop.

4. Handling with Raw Dog Food

Defrost each tub or bag of dog food in the fridge. The packaging will be airtight and leak-proof but as an extra precaution, place the raw dog food in the base of the fridge.

Once defrosted, never refreeze.

As the food defrosts, some liquid may appear in the packaging, always give these 'thaw juices' to your dog as they will be full of nutrients.
