One would wonder if science has actually defined the difference between non-hypoallergenic dogs and Hypoallergenic dogs accurately in this advanced day and age. Many would answer to the contrary. However, the fact remains that some dogs cause severe allergic reactions in people who happen be in the same room with the canine. The time it takes for a Hypoallergenic dog to cause an allergic reaction in a sensitive person in the room may vary from individual to individual.
So how does one go about determining which dog will not cause an allergic attack at any point in time? The trick here is to get yourself a hypoallergenic dog if you are a dog lover and are intent of having one as a pet and hope that the allergic attacks will be few and far between.
Now getting down to defining the difference between the two types of pets; a non-hypoallergenic dog is any dog that tends to shed a lot of fur or hair. Along with this shedding of hair the canine will also shed a lot of skin cells known as ‘dander’. This ‘dander’ along with the hair that spreads all over the house is what causes the allergic reactions in many people. Some canine breeds have a undercoat of hair to protect them from extremely cold temperatures, this is the cause of the frequent shedding of hair and is a very good trap for allergens such as the infamous dander.
Salivation is another cause of allergic reactions in people. Many dogs salivate more than the others. This canine saliva is rich in certain bacterium that most humans take to unkindly and as if that was not enough one has to contend with dog urine as well, which is a major cause of allergic reactions in humans.
Now for the more allergic friendly dogs around, the ones that cause little of no allergic reactions to their human friends, the hypoallergenic dogs. Most of these dogs do not have an undercoat of thick hair and so are not very ready to face cold weather, however they are just right for people with dog allergies. Hypoallergenic dogs hair resembles human hair a great deal and so it does not shed so easily. Some of these dogs do not have any hair on their bodies and are known as the hairless breeds and are not known to salivate as much as their allergy causing cousins are. When these dogs are done with their self cleansing duties they do not leave a whole lot of bacteria that gives their human masters an itch or a sneeze.
Some of the breeds that are known to be ‘allergy friendly’ include Bishon Frise, Maltese Terrier, Water Spaniel, Maltese, Terriers, Grey hounds and many more. A rule of thumb to follow when selecting a hypoallergenic dog is to ensure that it does not shed hair. This is the main indication that the dog will cause allergic reactions to people around him or her.
