The enzymes required to break down a high quality protein, raw meat and bone diet vs a high carbohydrate and processed diet are very different. The pancreas has to adapt to both the type and of enzymes it produces. Adding a probiotic supplement such as organic natural bio-live yogurt to your dogs first raw meals can make this transition easier.
The amount of bile required to break down raw food is substantially less because the food is 60% – 70% moisture. A dry food diet must be rehydrated before it can be digested, and the excessive amounts of bile in the gut help with this. Once you introduce a raw diet, your dog or cat may vomit bile as their stomach has not yet made adjustments to the amount of bile required for proper digestion. This is often temporary. Offering a dry treat can help settle the stomach if you notice your pet feels nauseous.
Dry food expands to 2x – 5x its size during digestion. This process stretches the gut and gives your pet a full sensation. Switching to a raw diet will mean a higher calorically dense diet, but with less volume. You may notice that your pet seems hungrier sooner (as the food digests quicker) and your pet may be asking for food more frequently (as they don’t get that full sensation). The stomach will adjust and these sensations will be less noticeable in 7 – 10 days time.
The gut flora (bacteria and enzymes) are different for dogs and cats fed a high carbohydrate-based diet vs. a high protein, raw meat and bone diet. It may take several weeks for your pet’s digestive flora to adjust. During this phase your pet may experience some excess gas, and may even feel nauseous.
Your pet’s stomach pH will change, as a high carbohydrate diet results in a more alkaline environment. As the stomach adjusts, it will create a strong stomach acid to break down foods quicker. This is healthier and more natural for your pet.
