Air Purifiers

I’m intrested in getting a rotweiller dog but I am concered about the dander because my grandpa and my dad are highly allergic to dander.

If I get a HEPA air purifier, encourage the dog to stay outside during nice days, use a special shampoo, special brush, and wips for the dog that eliminate dander. Will my grandpa and dad no longer have allergies?

Thank you for your time
PS: Versentil (or however your screen name works). Why don’t you stop being selfish and actually answer the question! I’m not being selfish because I’m conserned about my family. Get a life wemon and leave me alone. k bye

Does anyone recommend a specific shampoo for dogs that lasts long and smells good I have a dog who likes to step in her urine so she stinks. Also since we have carpet in our house we keep her in the laundry room or garage but she makes those rooms stink anyone recommend a good pet air sanitizer? Thanks
