Growling Tums Superfood Adult: Superfood Duck review

74.1/100Excellent
DryAdult

All four in our Excellent band, on one construction with the animal swapped. Fresh meat leads each label and the dried meat behind it does more of the work than the front of the bag suggests. The buffalo is the outlier, with three red meats and the range's only joint support.

Our view

Likely to suit

  • Owners who like the 65% animal share broken into its parts
  • Dogs better off cereal
  • Rotating proteins without changing the recipe underneath
  • A temperamental digestion, with prebiotic FOS and MOS in every bag
  • Older dogs feeling their joints, on the buffalo

Worth watching

  • No source for the omega 3 supplement, so none of the land-meat bags can be promised fish free
  • The buffalo blends buffalo with dried beef and dried lamb

  2. Superfood Salmon 75.5
  3. Superfood Duck 74.1
  4. Superfood Buffalo 73.4

All four Excellent. Typical dry food: Good.

A large itemised animal share and a light carbohydrate load carry all four, so the choice is which protein your dog gets on with.

A change of scene for a dog bored with the everyday birds, best kept to a busy one.

Every bag declares 65% animal content and itemises it, with freshly prepared meat at 35% and dried meat close behind. Sweet potato and beans take the place of cereal, beet pulp supplies the fibre, and a dried superfood blend, FOS at 192 mg/kg, MOS at 48 mg/kg and olive extract finish each list.

Carbohydrate converts to between 27.7% and 37.5% of dry matter, where the typical adult dry food runs at 46.2%. The omega 3 supplement gives no source on any label.
