AIBU to be upset my parents walked the dog in this heat?

Well if there had been an incident then it would be obvious

They were trying to do everything right in their book. Just forgot about OPs rules
I can understand this.

Parents should have lied. The dog wouldn’t tell.

Still likely

It I’m saying not everyone, unlike with a younger generation.

Not really
Plenty of people of that age are perfectly regularly messaging!

If they're in their 70s it's unlikely they're going to give the dog a strenuous walk.

I think you're massively ungrateful tbh. They're doing you a favour. Dog is fine.

A case of knowing too much through technology. Years gone by you'd happily know nothing about what time your dog got walked.

Such dogs tend to have far less fur and zero undercoat and aren't walked in the heat of the day, in really hot places its typical that no one does anything in the hottest part of the day!

In contrast our dogs in the UK have had to handle a jump from 13c here to nearly 30 in a space of perhaps 36 hours. My dogs are shedding handfuls of winter undercoat, despite me brushing them daily.

Dogs regulate temperature by avoiding activity that raises body heat, via insulation and panting - this is a very inefficient method if you are dragged out on a walk or encouraged to run around in the heat and given no time to acclimatise.

If you look at feral/wild dogs in hot countries they have pretty short coats, so undercoat sheds out easily, laze around in the shade all day and are active at dawn/dusk for the most part.

On the fence, we were on holiday with our dog. I stayed in the rental home for the hottest part of day with dog. We walked her first thing, carried her over hot pavements, it was breezy at the beach, she loved swimming, we carried water for her and a parasol. We would have gone straight back if she had shown any kind of discomfort. She’s a young dog. I don’t think 10.30 is too bad, but depends on the breed etc

26 is a bit hot but not walking your dog over 20 degrees? Why? What is going to happen at 20 degrees?
I think the world had gone mad over this. I'm a dog owner and I'll use my common sense. If it's too hot I'll get up early but at the minute not a day goes by without someone posting on Facebook that they saw a dog being walked. You know nothing about them they may have been going 5 min to the patch of grass because they don't have a garden. They may be walking 5 minutes to the woods where it's much cooler.
People need to mInd their own business.

Being in their 70s they probably don't naturally think about texting when in doubt. Also don't want to bother OP.

They probably thought your dog needed a wallk.

Dogs in hot parts of the world are used to those temperatures they are acclimatised dogs here in UK are not given temperatures we are currently experiencing are not the norm ! Go educate yourself God help any dog of yours

I took my dog during the high temperatures to the dog field where he has choice on how he spends the 50 minutes. He walked around the field 1.5 times sticking to the shade and spent the remaining 40-45 minutes lying in the shade. He knows his limits. Obviously most dogs will ignore their limits if they have no choice but to accompany their owners. Although my dog will do the passive lie down flat and refuse to take another step if I don’t get the message.

Professionals will ALWAYS err on the side of caution. That's why they tell everyone whose dog has eaten grapes to come in for an emetic. It's why humans are told that all cat and dog bites require medical attention and antibiotics.

My own dog struggles in the heat FWIW so I wouldn't walk him above about 22-23, but I don't feel like it's my place to dictate what others do. OP's parents shouldn't have walked her dog against her wishes but ultimately this is one of the risks of not paying for professional pet care.

It didn't happen to me doesn't mean the risk doesn't exist

Yep

Exactly
And it really isn't only old or ill dogs
At the end of the day its not legal requirement its advice and optional from experts
But, as with many aspects in life, plenty of people just think they know better

Exactly.

They've done you a favour and saved you a lot of money by looking after your dog. How they take care of the dog is up to them.

If you don't like how they do it, pay a professional.

The problem is that they were asked not to walk the dog in the heat and they did so anyway. They could have texted op saying look the dog is going mental, the heat feels alright for us to take him to a shady area, is that alright?

I’ve been walking my dog at 6:30am each morning but but 2.30 he’s barking to go out again. I think if you ask your parents to dog sit you just have to let them do it their way.

I agree with OP, it's the principle - they were asked not to walk the dog if it was over 20c and they did it anyway.
And to everyone saying "it was fine for the parents to be out in that heat so it was fine for the dogs" - were the parents walking on hot pavements in bare feet and wearing a fur coat?

OP, just don't ever leave your dog with them again

But no one whose dog ends up with heatstroke ever thinks it is their dog who is at risk! If they think of it at all, they conceptually believe it’s a problem that other dogs might have.
obviously some cope better than other, many people get away with it just fine. But no professional is going to advise something potentially risky, are they?

No - it’s proven risk for some dogs, not every dog.

Well yes
Following the advice from experts...isnt compulsory its just sensible?.
No one has said heat exhaustion will happen to every dog at all. Its you that is arguing this
They just dont want to put their dog at evidenced and scientifically proven risk
Its the last word that's key
