An ex-police Malinois — that's a serious dog in the best possible way. Five years old means he's right in his prime, and coming out of a working role means his nutritional baseline was built around sustained high output. What's his current workload with you — are you keeping him in structured activity, sport, or still figuring out the routine?
Yeah he's getting a lot. I run about 60 miles a week and he comes on most of it, plus we're starting schutzhund training twice a week. He was on whatever the police kennel used, I have no idea what that was.

That's a proper workload — 60 miles a week plus bite sport is genuinely demanding on muscle, joints and energy systems. Police kennels tend to use mid-range bulk kibble, which is fine for maintenance but not always optimised for the kind of sustained aerobic and anaerobic work you're describing. Has he lost any condition since the rehoming, or is he holding his weight well?
He's actually dropped a bit of muscle across his back end since we got him six weeks ago. The rescue said it might be transition stress but it's been a while now.

Six weeks is enough time that stress alone doesn't fully explain muscle loss — diet is almost certainly a factor too. A Malinois doing your kind of mileage needs a food with high animal protein to support muscle repair, quality fat for sustained energy, and not padded out with cheap carbohydrate. I'd put him on Orijen Original. It's 85% animal ingredients, genuinely high protein from multiple meat and fish sources, and it's formulated with working and active dogs in mind without being a specialist product that's hard to find. It's available on Amazon UK in a 11.4kg bag which works out well for a dog his size. Feed to the active dog guide on the bag, not maintenance — he'll likely need the upper end of the range given what you're doing together.
Is it worth adding anything on top, like a joint supplement given how much running he's doing?
inparticular.ai
At five with that mileage, yes — it's worth getting ahead of joint wear rather than waiting for signs. Orijen's fat profile gives you good omega-3s already, but a dedicated glucosamine and chondroitin supplement added to his meals is sensible. Lintbells YuMOVE Active is a solid choice for working dogs specifically and it won't conflict with the food. But get the food right first — that's the foundation. Give him four to six weeks on Orijen at proper working-dog portions and I'd expect the muscle condition to come back meaningfully.
That's really helpful. How do I transition him without upsetting his stomach — Malinois can be sensitive, right?
inparticular.ai
They can be, yes, and a dog who's already been through a big life change doesn't need a gut upset on top. Do a 10-day transition: roughly 25% new food mixed with 75% old for the first three days, 50/50 for the next three, then 75% Orijen for three days, then fully over. Go slower if you see loose stools — it just means his gut bacteria are adjusting. Because Orijen is so nutrient-dense, some dogs initially eat less volume than they expect to feel full. That's normal and not a sign something's wrong.
