Senior food for a 5-year-old Great Dane

Great Danes are one of those breeds where 'senior' arrives earlier than the calendar suggests — most vets consider them entering their senior phase around 5 to 6 years old, so you're genuinely right to be thinking about this now rather than waiting. Senior dogs typically need fewer calories to avoid weight gain, better digestibility to get more from their food, and solid joint support given the strain that comes with a large frame. What matters most is tailoring that to your specific dog — so: what's your Dane's name and current weight, are there any health conditions in the picture, and what are they eating at the moment?

Rula is a great name, and 62kg is a healthy weight for a female Dane. The fact that she has no conditions yet is exactly why now is the right time to act — you want to protect those joints and keep her metabolism dialled in before problems have a chance to start, not after. Eukanuba Large Breed Adult has served her well, but it's formulated for maintenance in adult dogs, not for the reduced calorie density and elevated joint support a Dane genuinely needs at this stage. A couple of quick questions: is she currently active on walks, and has she ever shown any stiffness after rest or exercise?

That morning stiffness is worth taking seriously in a breed like hers — it's a very early signal that her joints are starting to feel the load. It doesn't mean anything is wrong yet, but it does mean the nutrition piece matters more, not less. For Rula specifically, I'd recommend Hill's Science Plan Canine Mature Adult 6+ Large Breed with Chicken. I know '6+' sounds like it's for older dogs, but Hills specifically developed this formula with Great Danes and similar large breeds in mind, and vets regularly recommend starting it at 5 for this breed. It has controlled calories to prevent the gradual weight creep that stresses joints, added glucosamine and chondroitin at meaningful levels for a dog Rula's size, and it's highly digestible so she's actually absorbing what she eats. It's also a dry kibble like she's used to, so the transition should be straightforward.

Don't swap it over all at once — large breed stomachs can be sensitive and a sudden change can cause loose stools even with a good food. Do it over 10 days: start with roughly 25% new food mixed into 75% of the Eukanuba, then move to 50/50 around day four, 75% new by day seven, and fully switched by day ten. Given she's 62kg, check the feeding guide on the Hill's bag for her weight band and use that as your daily target — large breeds are often overfed and the calories add up fast. If the morning stiffness doesn't ease within 6 to 8 weeks of being fully on the new food, it's worth a vet check to rule out early hip or elbow changes.

Good call — you're genuinely ahead of the curve with this, and Rula's likely to thank you for it in a few years. Keep an eye on her weight every month or so, especially through winter when walks can get shorter. If anything changes with her mobility or appetite, it's always worth looping in your vet. Hope she gets on brilliantly with it.
