Feeding an older dog: a guide to senior dog food
Updated: 3d
Older dogs are a joy: calmer, wiser and endlessly loyal. As they slow down, their bodies change too, and their food may need to change with them. Here's how to feed your dog through their senior years.
When is a dog a senior?
It depends on size. Larger dogs age faster than small ones:
Small breeds (under 10kg): around 8-10 years
Medium breeds (10-25kg): around 7-8 years
Large and giant breeds (over 25kg): around 5-7 years
There's no need to switch on a birthday. Watch for signs that your dog's needs are changing.
Signs your dog's nutritional needs are changing
Putting on weight on the same amount of food
Sleeping more and slowing down on walks
Stiffness getting up, or reluctance to jump or climb stairs
A coat that is duller or thinner
Changes in appetite or digestion
Some of these can also signal health problems, so mention them to your vet. Many practices offer senior health checks.
How older dogs' needs change
Fewer calories
Less active dogs burn less energy, and it's easy for the pounds to creep on. Extra weight puts strain on joints, so keeping your dog trim is one of the kindest things you can do. Senior recipes are typically lower in fat and calories. Our Senior Turkey recipe has 9% fat and 343 kcal/100g, compared with 13% fat and 360 kcal/100g for our adult Lamb.
Quality protein
Older dogs still need good-quality protein to help maintain muscle. Look for a senior food led by named meat or fish, not one that has simply cut protein. Our Senior Turkey recipe is 50% turkey and 27% protein.
Joint support
Glucosamine, chondroitin sulphate and MSM are commonly added to senior foods. Our senior recipes include all three to help promote joint repair and mobility in the ageing pet.
Omega 3
EPA and DHA help support healthy joints, skin and coat. Both our senior recipes include added omega 3.
L-Carnitine
L-Carnitine helps the body use fat for energy. Our senior recipes include it to help maintain a healthy weight and promote lean muscle development.
Digestive health
Prebiotics MOS and FOS may help to promote the growth of healthy gut bacteria and aid digestion.
Our senior recipes
Grain Free Senior Turkey with Sweet Potato & Cranberry: 50% turkey, a lean, low-fat protein source.
Grain Free Senior Trout with Salmon, Sweet Potato & Asparagus: a fish-based option, naturally rich in omega 3.
If your dog is overweight rather than older, our Light recipes are designed for overweight dogs, with added L-Carnitine and joint support.
Practical tips for feeding an older dog
Weigh regularly. Monthly weigh-ins help you spot changes early.
Feed by body shape. You should be able to feel, but not see, the ribs.
Split meals. Two smaller meals can be easier to digest than one big one.
Keep water close. Make sure fresh, clean water is always easy to reach.
Raise the bowl if your dog finds bending uncomfortable.
Soften kibble with a little warm water if your dog has sensitive teeth.
Keep treats small. Use low-calorie rewards, or kibble from the daily allowance.
Keep them moving. Gentle, regular walks help maintain muscle, joints and weight.
Changing to a senior food
As with any change, switch gradually over around two weeks, mixing increasing amounts of the new food into the old. Older dogs can have more sensitive tummies, so take your time.
Frequently asked questions
When should I switch my dog to senior food? Usually between 5 and 10 years old, depending on size, or when you notice weight gain, slowing down or stiffness.
Do senior dogs need less protein? Healthy older dogs generally still need good-quality protein to maintain muscle. If your dog has a medical condition such as kidney disease, your vet may recommend a specific diet.
Can an older dog stay on adult food? Yes, if they're maintaining a healthy weight and doing well. Senior food is helpful when needs change, not compulsory.
What is the best food for an older dog with stiff joints? A recipe that helps keep weight down, with added glucosamine, chondroitin and omega 3, is a sensible choice, alongside your vet's advice.
My older dog has gone off their food. What should I do? A sudden change in appetite in an older dog should always be checked by your vet.
