World Record Large Ears

On September 2011, the Guinness Book of World Records announced the longest ears of any dog belongs to a Coonhound named Harbor. His magnificent ears measured 12.25 inches and 13.5 inches long (left and right respectively).

I wonder how much earwax he produces!

Kids Exposed to Fido or Fluffy in the First Year of Life Decreases Risk of Becoming Allergic to Them

There have been a number of studies in the past investigating whether it is healthy for a baby to be around pets and whether such exposure increases or decreases risk of becoming allergic to them later in life.

In a recent study (published online June 2011), the researchers found that among males, those with an indoor dog during the first year of life had half the risk of becoming allergic to dogs at age 18 compared with those who did not have an indoor dog in the first year of life regardless whether born by C-section or vaginally. Also, teens with an indoor cat in the first year of life also had a decreased risk of becoming allergic to cats. Neither cumulative exposure nor exposure at any other particular age was associated with either outcome. So it appears that the FIRST year of life is key to whether a child develops pet allergies or not.

Although in this study, cat and dog ownership appears to be beneficial in kids, prior studies have suggested that for at least cats, it increases risk of overall allergies in children by 13 times! Dog exposure, however, reduces overall allergy by 4 times.

Hypoallergenic Cats and Dogs

CBS news published a story on hypoallergenic pets on their website here.

The story did report that pricey pets that claim to be easy on allergy sufferers are probably more hype than true, but than did go on to list dogs and cats that are purportedly hypoallergenic.

The claim for hypoallergenicity is based on hair/fur/dander length or quantity... mainly the shorter or smaller the amount, the less allergenic. However, there are other reasons why hypoallergenic pets are NOT hypoallergenic. These include a pet's saliva and skin which contain the same protein that trigger allergic reactions.

Also, many dog allergy sufferers also have weed, tree, and grass allergies. If your hypoallergenic dog likes to roll in the grass and weed, they are getting that all over them and bringing it into the house and to you. So even if you are not allergic to the dog, you probably are allergic to what's on the dog.
