First of all everyone should know this answer. But in case you don't know sometimes someone as in your classmate can be allergic to any sort of animal. Sometime it just depends on the kind of pet. If it was to be a dog then there are quite a few reasons. This question is fairly easy to answer.
Many people do believe pets should be allowed int o classrooms because they think you can learn from them and they are cute but many see it other way. Some district dont want pets in classrooms because they pet has to be vacinated with rabies, salmonela, they cant have fleas or ticks. And if the pet bites a student the kid might get sick from it and could sue against the district.
