How death-defying is have fiberglas insulation blown contained by your house?

I have a dog next to congestive heart failure, and after I have the insulation blown 2 days later he go into heart failure. I know he's going to die from this disease; but it be brought to my attention that the insulation could be triggering attacks related to turning on the whole house devotee and air conditioning. I also hold concerns about my saftey and my other animals saftey (lungs).How death-defying is have fiberglas insulation blown contained by your house?
The process throws deeply of crud around while being done, but after that it is benign. I assume that some go into the attic, and that you have an attic exhaust aficionado. Running the fan will not raison d`¨otre problems, as the air flow is into the attic from the house, and after outside.
Get better air filter and yes it could be triggering the dogs attacks. In the future you should read and research better. Fiberglass insulation is harmful even for humans with on top form lungs. But thats hindsight in a minute.
