Are there any health conditions that prevent dogs or cats from having treats that are made from natural ingredients?

Natural treats are, in general, a great option for dogs and cats dealing with health conditions. As they're simply dehydrated there's no artificial preservatives, colourings or flavourings and they're made from high quality ingredients. Most are low in fat (please note, sprats, which are much higher in fat should not be given to pets requiring a low fat diet eg those with pancreatitis) As always, treats should be used in moderation as part of a healthy diet.
