The Facts About Gluten for Dogs

Gluten is the name of the protein found in wheat. Similar proteins are found in rye, barley and oats. However, wheat is the only one considered to contain ‘true gluten’. Rice and corn (maize) are considered safe for animals and humans that have a gluten intolerance.

• Wheat contains proteins called GLIADIN + GLUTENIN
• Rye contains a protein called SECALIN
• Barley contains a protein called HORDEIN
• Oats contain a protein called AVENIN

Hidden sources of gluten include:

…some medications and antibiotics, additives, stabilizers and preservatives. Caramel colouring (found in some tinned pet foods, used to produce the brown ‘meaty’ colour) can be made from barley.

Oats are not considered to be a problem for animals or people who are allergic or intolerant to gluten. Many coeliacs can tolerate oats. Occasionally oats may cause a reaction as there may be cross-contamination with other grains during the milling process.
