At the age of 5 my grandpas long haired mongeral would make make really ill, rashes, puffy itchy eyes, weezing the lot. My Grandads whippet never bothered me in the slightest.My aunties boxers also made me ill. My doctor told my parents i would never be able to get a dog.
Anyway come 14yrs of age i got a whippet and i was fine, following this, two border collies and a jack russell terrier. I have had many dogs since and also worked in a dog grooming parlour.
Yes i am allegic to dogs, but you do find that some breeds are worse than others. Its not just down to how short their hair is.
