Who on earth thinks it's their right to throw treats to someone else's dog ?!

[Pollydon]

.......or an animal owned by someone else ( my cousin has horses, I know this happens to her too)
So I have a big, daft, friendly labrador. He is getting on a bit and has a sensitive tummy. I live abroad but on an urbinization with a high % of british residents and holiday home owners ( so, no language barrier in this case). I've posted about this cretin man before over Christmas, he insists on throwing handfuls of dog treats to all the dogs he sees on walks. Luckily he has to leave after 90 days due to Schengen rules)
Well, he is back . In the intervening months my boy has been diagnosed with under active thyroid and has started medication. The rules around food and medication are very strict. The results have been fabulous, my boy has got his spark back, he is playful and active again.
So, this man threw his handful of treats again this morning. I told ddog to leave, which he did, then I told the man why ddog CANNOT have any treats. His reply ? " Well, I enjoy seeing the dogs get their treats so I'm not going to stop 😡"
I'm fucking fuming tbh, who the hell does he think he is ? He has no idea if any of the other dogs he does this to have allergies ect.

My next door neighbour is elderly and keeps a bag of dog treats at her door.all the dogs get offered a treat as they pass by.which I think it’s lovely.All you have to do is say no thanks.My dog has been treated for years with thyroid medication and the odd treat doesn’t harm.Your dog was well behaved enough to ignore the treat anyway.He’s just being nice I think.I know it’s hard with a dog with sensitive stomach but it’s sounds like your dog is well trained.

It is wrong but unfortunately it's not illegal.

I'm not sure there's anything you can do except avoid him and put your dog on a lead whenever you have to pass him.

PP's example of the lady offering treats is totally different. Offering and listening when the owner says "no" is absolutely fine, but chucking the treats all over the floor without asking permission or checking with the owner is a) rude and b) potentially very dangerous as it could make a dog sick.

That is totally different. An older man lost his ddog and would call us over to his patio to give ours a treat, once we explained but let him know that our boy was just as happy with a bit of fuss he totally understood and our ddog goes to say hello to him every morning.
Also you may have missed the part where I said that my boy has a very sensitive tummy. Cleaning up diarreahoea from a 7 stone dog is not pleasant, nor is having diarrhoea pleasant for the dog.

It's mindboggling isn't it "Well, I enjoy seeing the dogs get their treats so I'm not going to stop".... so, completely aware that he's putting his own enjoyment before the dog's wellbeing!

If he absolutely insists is it possible to keep some of your dog's daily portion aside to take with you on walks and that way you can ask him to give something that isn't going to make your dog ill?
Or avoid and shout "do not feed my dog, it could kill him".

There's an elderly guy who lives near me that is clearly very lonely, he waits for dog walkers and rushes out to give them a treat (I've got two chihuahuas, one who we've had to be very careful with his weight management and the other is on grain free due to seizures) and the first time he saw us he'd given them each a biscuit about the size of their heads before I'd noticed what he was doing.
