Five whole cooked fillets steamed and handmade, in a 22 g pack. Neither fried nor dehydrated: steam sets the protein without drying it, so the fillet breaks by hand into whatever piece you want.
The ingredient list of these five products fits on one line.
Between 99.5% and 100% of the content is the muscle the product is named after. The rest is that meat or fish’s own fat: between 1.5% and 2%. No cereals, no preservatives, no by-products.
Chicken and duck, the two white meats in the range. Easy digestion and a gradual flavour.

It is what sets this range apart from the other treats in the catalogue.
Steam cooks the protein at a moderate temperature without contact with fat. The result is a tender fillet that can be broken by hand into portions, rather than a hard piece to gnaw.
This also keeps the ingredient list to a single line: nothing needs to be added to hold its shape.
The packaging bears a seal stating free from poultry by-products. This means the contents are identifiable muscle, not meal or cutting scraps.
On the chicken and duck fillets, this seal does not mean poultry free: it means free from poultry by-products.
These are complementary snacks: they do not replace the daily ration. The usual guideline is to keep treats below 10% of daily calories.
A 22 g fillet is a reasonable portion for a medium-sized dog; divide it for smaller dogs.
As this is cooked rather than dehydrated, seal it carefully and refrigerate after opening, then use within a few days.
