Being around hypoallergenic dogs reduces the risk of allergic attacks as compared to being around non-hypoallergenic dogs; not a big difference but an important one. Those who want to own a dog as a pet but are allergic and cant stay with them for long; feels frustrating. Such people can own a hypoallergenic dog which does not spread much allergen all around your home compared to the non-hypoallergenic ones. The allergic attacks won’t stop, but will become far less frequent.
The fur of non-hypoallergenic dogs is usually dense and loose resulting in lot of shedding and presence of dander too. Dander comprises of all the dust particles, skin cells and other harmful particles that float in the air. Due to shedding of this dander, people get frequent allergic attacks. These dogs have a thick undercoat which is the reason of frequent shedding and it also traps the dander and allergens floating in the surrounding air.
Certain non-hypoallergenic breeds tend to salivate a lot; another thing which increases the rate of allergic attacks. It is the presence of bacteria in the saliva to which most of the people are allergic. These dogs expel saliva without having any control over it, making it difficult for allergic people in their presence. The urine of dogs can contain bacteria; another element causing allergic attacks.
The undercoats of hypoallergenic dogs [http://www.dogtalkies.com/2009/01/30/increase-the-life-of-your-dog-by-nursing-his-oral-health/] is very thin or absent, making them vulnerable to cold, but perfect for those owners who suffer from allergic attacks. Shedding of hair is very less in the case of these dogs as the hair is much like what we humans have. To make sure their hair does not grow long, they need to be trimmed from time to time. Some hypoallergenic dogs do not have hair at all, though their skin needs to be taken care of properly.
The amount of saliva that hypoallergenic dogs expel is very less compared to the other breeds, resulting in less amount of bacteria; good for allergic people. Their urine is also found not to affect allergic people much.
Some of the popular hypoallergenic breeds that people commonly own is the Greyhound, Terrier, Bishop Frise, Maltese, Irish Water Spaniel, Schnauzer and Portuguese Water Dog. It is easier to find the breeders of these dogs in your locality.
If you learn how to groom these dogs well, brushing them and caring for them regularly, they will easily live for twelve years at least. They are very much friendly and love exercising.
