Straight to it: in a UAE summer, your senior dog's heart is already working overtime before they've taken a single step out the door. So the plan is simple, walk in the cool hours, keep water everywhere, watch the breathing, and please don't write off heat-driven tiredness as “he's just getting old.” Some of it might be the heat leaning on a heart that's already busy.
Let me explain what's actually happening, and exactly what I'd do if this were my dog.
Dogs don't sweat the way we do. They cool down mainly by panting, and here's the part people miss: panting is work for the heart. Faster breathing, a faster heart rate, blood vessels opening up to shed heat, it all adds up to more demand. A young, healthy heart shrugs that off. A senior heart that's already quietly compensating for a leaky valve has a lot less spare capacity, so a hot day eats into its reserve fast. Add our humidity, which makes panting less effective, and you can see why summer is the season I worry about most for my heart patients.
A few figures. Pavement out here can climb past 60°C in peak summer, hot enough to hurt paws in seconds. A dog's normal body temperature sits around 38 to 39°C, and once it pushes past roughly 40 to 41°C you're heading into heatstroke territory, which is a genuine emergency. And that calm resting breathing rate we care so much about, under 30 breaths a minute, gets muddy in summer, because normal panting and heart-related breathing can look alike. So do your breathing checks when your dog is cool and settled indoors, not right after a walk.
The walks are the easiest win. Go early morning or late evening, and skip the midday furnace entirely. Quick pavement test: press the back of your hand to the ground for seven seconds, and if you can't hold it there, it's too hot for their paws and too hot for their heart. Keep the pace gentle and the sessions short, this really isn't the season for heroics. On the brutal days, honestly, just stay in, 8 Indoor Activities for Dogs During the UAE Summer has plenty to keep them busy.
Hydration does more than you'd think. A well-hydrated dog handles heat better and puts less strain on circulation. Keep several bowls of fresh water around the house, and adding a splash of water to meals is an easy way to sneak a bit more fluid in. If you want the bigger picture on living with our climate, A Dog Parent's Guide to UAE Summers covers it nicely.
This is the one. Heavy panting, tiring on a walk, wanting to lie down, in summer it's tempting to shrug and say “it's just hot.” And often, it is. But those exact same signs show up when a senior heart is struggling, so the two hide behind each other beautifully. My rule of thumb: if the panting doesn't settle once your dog is cool and resting, or you're seeing more of it than the weather alone explains, that's a conversation with us, not a shrug.
Know the emergency signs, because here minutes genuinely matter: relentless heavy panting that won't ease, heavy drooling, gums going brick-red or pale, wobbliness or collapse, vomiting or diarrhoea. If you see these, move your dog to shade or AC, wet them with cool (not ice-cold) water, and get to a vet immediately. For a dog with a heart condition, overheating is doubly risky, so please don't try to tough it out.
None of this is about wrapping your dog in bubble wrap for four months. It's about small, smart adjustments, cooler walks, more water, honest attention to their breathing, so a senior heart isn't fighting the weather and the disease at the same time. Do that, and most heart-dog summers here pass just fine. And if you're ever unsure whether it's the heat or the heart, that's exactly what we're here for, just message us.
