Hypo allergenic dogs  

I have 2 rat terriers and a chihuahua and my rats shed....so I have a hepafilter vacume that is great, no bags and just empty the container and wash the filter ocassionaly and keeps control.The weirdest thing is , one of my rats , sheds more then the others....have no clue why...

It's actually not dog hair or fur that people are allergic to. It is the dander. "Hypo allergenic" breeds like your dog don't produce as much dander as other breeds of dogs. This could be because of they have hair instead of fur. I'm not sure exactly why, just that they don't produce as much dander. Most people with pet allergies aren't affected by the small amount of dander they do produce. However, a few people who have extremely sensitive allergies are still affected by these "hypo allergenic" dogs. It's not very common, but there are some people out there that are just that allergic.

I've heard that yorkshire terriers are also hypo allergenic. I've also heard that many "designer breeds" or "hybrids" like yorkiepoos (yorkshire terrier and poodle mixes) and labradoodles (labrador retriever and poodle mixes) are also hypo allergenic.
