Dorwest Tree Barks Powder - 100g is a natural digestive support supplement for dogs and cats. It’s made from finely powdered tree barks (such as slippery elm and white poplar, often with marshmallow root) that swell and become soothing when mixed with moisture, helping to coat the digestive tract. This action can slow food passage, increase nutrient absorption, ease discomfort, and help firm stools — useful for upset tummies, diarrhoea, weaning, recovery from illness, and general digestive support. 

Here is how it helps support digestion.

  • Slippery elm bark - contains mucilage, a sticky substance that helps maintain good bowel regularity and stool consistency.
  • Marshmallow root - another powerful mucilaginous herb that coats the gut, soothing and assisting gut transit.
  • White poplar bark - helps to keep tummies comfortable, thanks to its soothing properties

Which dogs can benefit from Tree Barks Powder?

Digestive upsets are very common in pets. Symptoms such as noisy stomachs, excess gas, nausea, reduced appetite, and loose or frequent stools can all indicate that the digestive system is unsettled. These issues may be triggered by medical conditions, stress, dietary changes, environmental changes, or simply eating something inappropriate.

Tree Barks Powder can be helpful for both short-term digestive disturbances and ongoing sensitive stomach concerns. It works to gently calm and support the digestive system, making it suitable for extended use if needed. Because of its mild and natural action, it can also be given to pets of all ages, including young puppies and kittens during the weaning stage.

How does Tree Barks Powder work?

Tree Barks Powder is a soft, fine powder that changes texture when it comes into contact with moisture. Once damp, it forms a thick, soothing gel-like consistency. In the digestive tract, natural moisture activates this process, allowing the mixture to coat the lining of the stomach and intestines.

This protective coating helps calm irritation, slows the movement of food through the gut, and supports healthy digestion. By doing so, it promotes proper nutrient absorption and helps maintain firm, well-formed stools.


Is suitable for pets of all ages, including puppies and also bitches during pregnancy and lactation. Tree barks can also be given in conjunction with other medications.
