Senior German Shepherd Food Advice at 7

A dulling coat and dropping energy in a 7-year-old German Shepherd is genuinely worth paying attention to — those two things together are often a signal that the food isn't keeping up with where your dog is in life. German Shepherds are considered mature from around 5 and hit senior territory by 7, so this is exactly the point where nutrition can make a real visible difference. To make sure I point you in the right direction: is your GSD male or female, roughly what weight are they, and what are they currently eating?

That makes a lot of sense. Pro Plan Adult Large Breed is a solid food, but at 7 it's no longer quite the right tool for the job. The protein and fat balance is calibrated for a younger adult dog with a faster metabolism. At this stage, she needs food that supports joint health more actively, has adjusted phosphorus levels to ease the load on her kidneys, and — critically for that coat — has higher levels of omega-3 fatty acids, particularly EPA and DHA. Is she on any joint supplements at the moment, or just the food?

You won't need to add fish oil separately if you switch to the right food — that's one of the things that should come built in at this life stage. Based on everything you've described, I'd go with Royal Canin German Shepherd Adult 5+. It's breed-specific, which matters more than people think with GSDs — it's formulated for their particular digestive sensitivity, their long double coat, and their predisposition to joint issues. The kibble shape is also designed for their jaw. The EPA and DHA levels are meaningfully higher than a standard adult food, which is what will bring that coat back. You should see a noticeable difference in coat condition within 6 to 8 weeks of switching. It's available in 3kg and 11kg bags on Amazon UK — the 11kg is much better value if she's getting through it steadily.

With some breeds, I'd say the difference is marginal. With German Shepherds, it's genuinely meaningful. GSDs have a well-documented tendency toward digestive sensitivity — loose stools, gas, variable appetite — and Royal Canin's GSD formula uses highly digestible proteins and a specific fibre blend to address that directly. The coat formula is also tailored to the double coat, not just a generic skin-and-coat blend. And the joint support is calibrated for a large breed with the GSD's particular build and movement. It's not marketing fluff — the R&D behind breed lines at Royal Canin is real. That said, if she were a mixed breed or you wanted an alternative, I'd look at Hills Science Plan Mature Adult Large Breed as a strong runner-up.

Never go straight over, especially with a GSD — their digestive systems really don't like sudden changes. Do a gradual transition over 7 to 10 days: start with about 25% new food mixed into 75% old, then move to 50/50 around day four, then 75% new by day seven, and fully switched by day ten. If she's prone to loose stools at any stage, slow down and hold that ratio for an extra couple of days before moving on. Once she's fully transitioned, give it the full 8 weeks before judging coat improvement — that's how long it takes for a full coat cycle to reflect the change in nutrition.
