Caring for Your Senior Dog in the Summer Months

Summer is wonderful. Long evenings, open fields, and more time outdoors with your dog. But if your dog is getting on in years, those warm months can bring challenges that younger dogs simply do not face.

Senior dogs feel the heat differently. Their bodies are less efficient at keeping everything in balance, and the knock-on effects of hot weather can touch everything from their joints to their kidneys. The good news is that with a few thoughtful adjustments, you can make summer much more comfortable for them.

Here is what to know, and what to do.

As dogs age, their internal systems slow down. Their ability to regulate body temperature becomes less reliable. Their organs work harder under stress. Their joints, which may already be stiff or inflamed, can be affected by the heat in ways that might surprise you.

None of this means your older dog cannot enjoy summer. It just means they need a bit more looking after during it. If you have ever wondered whether your dog is actually older than you think in human terms, our guide Dogs Are Older Than You Think is worth a read before diving into this one.

Most owners know that cold, damp weather is rough on arthritic dogs. Stiff mornings, slow starts, reluctance to go downstairs. It makes sense: cold causes muscles to contract and joints to seize up.

What is less well known is that extreme heat can cause its own joint problems, and for a different reason entirely.

High temperatures can increase systemic inflammation in the body. For a dog already dealing with arthritis in dogs, summer in the UK can therefore bring a double blow: the warmth might ease the initial stiffness, but if temperatures climb high, that underlying inflammation can flare. You might notice your senior dog seeming more uncomfortable or reluctant to move during the hottest part of the day, even though it is not cold.

Add to that the fact that older dogs are often on reduced exercise anyway, and the muscles that support those achy joints can weaken over summer if activity drops too sharply. The key is keeping them gently moving, not stopping altogether.

Joints are the visible concern, but hot weather puts quiet pressure on two organs that older dogs often already have less reserve in: the heart and the kidneys.

The heart has to work harder in the heat because the body is constantly trying to cool itself. Blood is redirected to the skin's surface to release heat, which means the heart pumps faster and harder. For a young, healthy dog this is fine. For an older dog whose heart may not be quite as strong as it was, this extra workload adds up quickly.

The kidneys are under pressure for a different reason. Dogs lose fluid through panting, and if that fluid is not replaced fast enough, the kidneys have to work harder to concentrate urine and maintain the body's fluid balance. Older dogs are also more prone to kidney issues generally, so dehydration in summer is a more serious concern for them than for younger dogs.

Signs to watch for include increased tiredness, reduced appetite, very dark urine, or a dog that is panting more than usual without obvious reason. If you notice any of these, fresh water and a cool spot are the first steps, but contact your vet if symptoms do not improve quickly.

Keeping fresh water available in multiple spots around the house and garden is one of the simplest and most effective things you can do for a senior dog in summer.

When it comes to cooling an older dog down, there is one thing worth knowing that many people get wrong: avoid drastic temperature changes.

Going from a very hot garden straight into a very cold paddling pool or an air-conditioned room can be a shock to the system, particularly for older hearts and joints. Instead, aim for gradual cooling. A damp towel laid flat on a cool floor, a fan on a low setting, or a shaded outdoor space with a breeze are all kinder options than sudden cold.

Walk timings matter enormously. During summer, shift your walks to early morning or late evening when the air temperature is lower and the ground is not dangerously hot. Pavements hold heat long after the sun has moved on, and older dogs with sensitive paws or slower movement are at greater risk of burnt pads and heat exhaustion during midday walks.

A useful test: place the back of your hand on the pavement for five seconds. If it is too hot to hold there, it is too hot for your dog's paws.

Keep exercise gentle and consistent. For senior dogs with arthritis or mobility issues, short and frequent movement is better than one long walk. A ten-minute amble in the morning and another in the evening, with some gentle sniffing and exploring, keeps the joints moving without overdoing it. Swimming, if your dog enjoys it and has access to calm water, is brilliant for older joints because it builds muscle with minimal impact.

Cool resting spots. Make sure your dog has access to cool tiles or a cooling mat. Raised beds allow air to circulate underneath, which can help on warm nights. If your home gets very warm, close curtains during the hottest part of the day to keep rooms cooler.

Good daily nutrition and targeted supplementation can make a meaningful difference to how a senior dog copes with summer, both day to day and over the long term.

If your dog is showing signs of stiffness, reduced movement, or general discomfort, their joints need consistent support, not just when things get bad. Our Mighty Mobility Bundle is designed exactly for this. It brings together a comprehensive joint supplement and our Beef Bone Broth Powder, which provides essential nutrients that support joint health and also encourages better hydration, which as we have covered, matters a great deal in summer.

The joint powder supports flexibility, strength, and overall joint comfort from the inside, which is particularly valuable during a season when inflammation can creep up quietly. Consistency is key with joint supplements: the benefits build over time, so daily use through summer and beyond is the approach that makes the real difference.

Senior dogs are often very good at hiding discomfort. It is a natural instinct. So it is worth knowing what more subtle signs can look like in the heat:

• Seeking shade or cool spots more than usual

• Slower to get up from rest, or reluctant to lie down

• Eating or drinking less than normal

• More panting than the temperature seems to warrant

• Confusion or seeming a bit lost or unsettled

Any of these, particularly if they come on suddenly or feel out of character for your dog, is worth a call to your vet. Senior dogs can deteriorate faster than younger ones once something goes wrong in hot weather, so erring on the side of caution is always the right call.
