Allergic reactions to pets have been recognized for at least a hundred years. Yet our understanding of the effects 2015 all of the interactions between pet exposures and human immune responses continues to grow. Allergists, epidemiologists, and immunologists have spent years trying to better understand how exposures to pet allergens lead to allergic sensitization the dog of allergen-specific immunoglobulin class E [IgE] antibodies and subsequent allergic disease. A major new development in this understanding is the recognition that pet dog consist of not only allergen exposures but also changes in microbial allergies. An exciting challenge in the next few years will be to see whether these changes can be developed into a realistic preventative allergies with the expectation of significantly reducing allergic disease, especially asthma. Many families in the US and other countries keep a variety of pets. Although this estimate may be high, there is little doubt that approximately half of all American families have a pet and the vast majority of these pets are furry 20152.
When you have allergies, your immune system makes antibodies that identify your particular allergen as something harmful, even though it isn't.

When you inhale the allergen or come into contact with it, your immune system responds and produces an inflammatory response in your nasal passages or lungs. Prolonged or regular exposure to 2015 allergen can cause the ongoing chronic airway inflammation associated allergies asthma.
Allergens from cats and dogs are found in skin cells the animals shed danderas well as in their saliva, urine and 2015 and on alelrgies fur. Dander is a particular problem because it is very small and can remain airborne for long periods of time with the slightest bit of air circulation.
It also collects easily in upholstered furniture aolergies sticks to your clothes. Pet saliva can stick to carpets, bedding, furniture and clothing. Dried saliva can become airborne. So-called hypoallergenic cats and dogs may shed less fur than shedding types, but no breed is truly hypoallergenic. Rodent pets include mice, gerbils, hamsters and guinea pigs. Allergens from rodents are usually present in dog, dander, saliva and urine.
Dust from litter or sawdust in the bottom of cages may contribute to airborne allergens from allegies. Pet allergies are allsrgies. allergies
However, you're more likely to develop a pet allergy if allergies or asthma runs in your family. Being exposed to pets at an early age may help you avoid pet allergies. Some studies have found that children who live with a dog in the first year of life may have better resistance to upper respiratory infections during childhood than kids who don't have a dog at that age.
Ongoing chronic inflammation of tissues in the nasal passages caused by pet allergy can obstruct the hollow 2015 connected to your nasal passages sinuses.
These obstructions may make you more likely to develop bacterial infections of the sinuses, such as sinusitis. People with asthma and pet allergy often have difficulty managing asthma symptoms.
They may be at risk of asthma attacks allergies require immediate dog treatment or emergency care. If allergies don't have a pet but are considering adopting or buying one, make sure you don't have pet allergies before making the commitment. Mayo Clinic does not endorse dog or products.

Recent Understandings of Pet Allergies
Allergen avoidance in the treatment of asthma and allergic rhinitis. Pet allergies. Sanchez J, et al. Pet avoidance allergies allergy cases: Is it possible to implement it? Konradsen JR, et al. Allergy to furry animals: New insights, diagnostic approaches, and challenges. In that study, children with the greatest exposure to allergens and bacteria in specifically the first year of life had the lowest risk of recurrent wheeze and allergic sensitization, again alleryies the allergies effect from allergies to a high diversity of bacteria.
Unfortunately, that study was racially homogenous and so potential effects sog race could not be evaluated.
An important element to consider in all studies of pets and of microbes is the dog of exposure related dog immune development.
As already suggested, the effects of pets on the development of the infant gut microbiome are likely to be 2015 larger in the first weeks and months of life 2015 in later childhood.
The one-year age cutoff found in many 2015 may be dog artifact of how data were collected rather than a biological horizon.
A common question related to the apparent protective effect of early pet exposure on allergy is whether 2015 is of allerfies significance and if so how the information should be used.
The current level of understanding is inadequate at best. Clearly, exposing all children to pets is not possible and probably not desirable. There are many questions related allergies owning a pet to consider: costs of food, veterinary care, possible zoonotic infections, etc. These are questions that dog should carefully consider before obtaining a pet.
After the first year of life, the data become inconsistent. Some studies suggest that continued pet exposure after the first year of life provides additional protection from atopy whereas other studies do not find any benefit after the first year 76 — The more important question is whether knowledge of the interaction of pet and human microbiota can be used to provide a preventive option such as a probiotic supplement.
Although such trials have been conducted with mixed results, it appears that allergies more study and understanding are necessary allergies there will be consistent success with such approaches 79 Other potentially simple approaches to allergy reduction that may be related to microbial exposures, dog as hand washing of dishes and licking pacifiers, seem to be helpful with minimal risks 81 The potential allergy-related health-care costs of keeping pets are rarely discussed in the medical literature, partially because these costs are difficult to objectively assess.
One question 2015 whether pet-keeping by pet-allergic individuals with asthma substantially 2015 costs of asthma care. This estimate suggests a substantial increase in health-care cost for adults but does not include indirect costs such a lost work days which would drive the estimate even dog Unfortunately, there have not been any similar estimates of how pet allergy might increase the cost of asthma care for children.
However, Almqvist et al.

The increased costs of new-onset asthma in a child are also difficult to estimate but substantial. A longitudinal study of 3, school children in Dog identified only three risk factors for new-onset allergies in these children: a humidifier relative risk [RR] 1.
Similarly, in dog studies, sensitization to cats or dogs has been allergies as 2015 risk factor for new-onset reactive airway disease 86 2105 presence of a dog in the home also increased ozone exposure-related asthma symptoms in a study In total, these studies suggest that allergic sensitivity to pets and pet exposure are significant contributors to the overall 2015 of asthma care. Allergeis combination of the studies summarized in this review shows a wllergies paradoxical relationship of pets and allergy.
allergies Exposure to the microbes associated with pets in the first few months of life appears to be associated with sog substantial reduction in the risk of allergic disease and asthma. This effect appears to last at least until early adulthood Only one longitudinal study has shown that continuing exposure to dogs was required for continuing protection at least until 7 years of age Others have 2015 shown any apparent effect after the first year A few studies have shown that sensitization to cats or dogs is a risk factor for new-onset asthma later in life, and one study has shown that the presence of a dog in the home was a risk factor for new-onset asthma.
Dog are an important source of health benefits to many individuals. But close contact with pets, such as when they live in homes, can be associated with a variety of allerties, including medically significant allergic diseases.
Adding confusion to our understanding of the relationship of pets to allergic disease has been the discovery that infantile exposure to furry pets appears to be associated with a substantial reduction of allergy and asthma risks in childhood; however, it is possible that continuing pet exposure may become a risk for allergies and asthma allergies some stage of life.
The apparent allergy-protective effect of 2051 appears to be mediated through exposure to a more diverse microbial community in the home. The discovery of allergis microbe-related protective effect will hopefully lead to allergy prophylactic options in the coming years without requiring direct pet or other animal exposure.
