That is the cost of living in a tropical climate. Yes they are very very mean and hurt a lot. If I get any of their genes in my packages I kill the queen and start a new one from a good hive. The Africanized honey bee (killer bees) can not survive anywhere that it freezes. Honey bees leave their stinger behind when they sting you because it is barbed
And they die as a result. Smells are a huge part of a honeybees world. Example, one bee stung the dog and gave off a smell that marked it as a enemy and says sting here.
A exterminator may be able to remove/ kill them. When they sting you they are injecting a poison, so for animals and people who are not stung on a daily basis and have built up a resistance to it how many times you can be stung before dieing is purely a scale of how big you are. Sorry for your friends dog I am glad I don't have to deal with them, I try and get my bees from Northern California or farther north. Tuesday I was stung 50+ times without swelling. Any more questions I can answer.
