Man Refuses Entry to Friend's Girlfriend's Service Dog At Party, Sparking Heated Argument
Different people adore dogs for a variety of reasons. They are intelligent, adorable, and unconditionally loving—not to mention that they are the furry best buddies you never knew you needed.
Our dogs play a vital role in our everyday existence. They cooperate with us in many ways, obey our instructions, and are obedient friends.
Research has indicated that dogs are good for your health. Their skills are combined with training to enable service dogs to carry out particular duties for people with impairments.
Currently, a wide variety of breeds of service dogs are trained to help people with disabilities by doing a range of duties. However, did you know that some dogs can help control your diabetes and perhaps save your life?
Now that is one more item to put on the list. Severe blood sugar variations in diabetics are risky and can cause major long- and short-term health issues.
In particular, diabetic service dogs are taught to assist their owners when their blood sugar levels are abnormally high or low. The OP of today's story dislikes cats and dogs of any sort.
OP's friends know this, and primarily, he thinks they are filthy, so he wants nothing to do with them because of that. OP hosted a pumpkin carving party for his friends, only for one of them to show up with a dog.
This dog was a service dog for diabetes, and it belonged to the friend's girlfriend. The OP wanted the dog gone, but it came with a lot of backlash.
The OP writes

The party was indoors as its still nearly 100 during the day where he's at

OP has offered the following explanation for why they think they might be the a-hole:
AITA for not letting a service dog into my house? I might be the asshole because I was essentially keeping an important medical device away from my buddy's girlfriend.
We've gathered some of the most upvoted comments from the other Redditors for you to read through below

OP's buddy should have given him a heads up beforehand

This Redditor believes that something is missing

This Redditor doesn't want to get started in how the OP talks about cats and dogs

It's the OP's right not to allow a service dog in his private home

You don't just assume an animal is welcome when going to a private event

The OP doesn't have to let animals inside his home if he doesn't have to

They would not be an AH for declining the invitation

OP's tone might have been harsh

You don't just bring an animal to someone's house

A service dog is trained to do a specific task that increases the amount of time a person with a disability may engage in daily life. Some Redditors say OP does not discriminate on the basis of handicap as he's only enforcing a home rule.
If it had been another dog owner, nothing would have changed; the impairment is unrelated to this circumstance. Still, the story was given an everyone sucks verdict.
