Pero Working & Sporting: Working Dog Maintenance review
On this range the name on the bag matters more than the range. The Lamb & Rice Performance recipe names its animal at 39%, writes out a full list and reaches our Good band. Working Dog Active sits in Average and the other two rations in Poor, all three written in the broad language of the working shelf.

Our view
Likely to suit
- Working and sporting dogs on the lamb recipe, with fat at 15%
- A dog kept to one meat: lamb, lamb tallow and lamb gravy are the only animal entries in the lamb recipe
- Glucosamine and chondroitin, printed in the lamb recipe beside seaweed and cranberry
- Dogs who do fine on rice and barley
- A yard feeding several dogs a simple, familiar ration
Worth watching
- No species named anywhere on the three Working Dog rations, so no elimination diet on them
- Maintenance at 6% fat and Premiwm at 7% are modest for a dog that works
- Fish meal in Working Dog Active, so that one is not fish free

Named ingredients
Against the range
- Protein and fat, declared
- 19% and 6%
- Lightest in the range; the lamb recipe is 27% and 15%.
- Carbohydrate, dry matter
- 60.8%
- Highest in the range.
This reads more like a resting ration than a working one.
Only the Lamb & Rice Performance recipe writes its ingredients out by name, and every animal entry on it is lamb. The three Working Dog rations use the trade categories of the working shelf: cereals, meat and animal derivatives, oils and fats. Active adds fish meal, pasta and linseed oil to its list.
What varies most is fat. The lamb recipe declares 15%, Active 10%, Premiwm 7% and Maintenance 6%. None of the four prints a moisture figure, so every dry matter reading rests on the standard 8% kibble assumption.
