It's a peptide. It's not necessarily the same peptide for every person, and certainly not for every type of animal (if it were, anyone who was allergic to dogs would also be allergic to cats, rats, bears, monkeys and probably people).
But if there is a protein common to the dogs and the cats and say, horses too, then a person allergic to that protein all these animals have in common could have an allergic reaction to all these animals.
Some people are allergic to gluten while others are not. Gluten makes people allergic to it sick with celiac.
Mosquito, and it does not make all animals itch. The only reason it makes humans itch is because we have an allergic reaction to their saliva.
If you are allergic to something, you will break out in a rash with red itchy bumps. You may have symptoms like watery eyes, stopped up nose, or swelling. Severe allergic reactions involve swelling inside the bronchial tubes, leading to difficulty breathing and even death.
Cats
in doodyville, people take dumps. In the peanut gallery people allergic to peanuts get assasinated.
They are hyperallergenic (people cant be allergic to them) because they have hair, not fur like most dogs do. But they can have allergies of their own. For example, mine is allergic to chicken. Its not life threatening or anything but it just makes her extremely itchy.
Hopefully around 7.4 as with most people and animals. This makes people and animals ever so slightly alkaline.
its possible, what type of reaction do you have. Some people get migrains from certain fruit, and some fruit makes people's skin hurt
Note with any breed of dog (and also cats) the animals's saliva can also make you itch or provoke allergic reactions. Wash your hands after patting, and don't rub your eyes. Gradual exposure is part of the answer. Animals that lick themselves, such as cats, are therefore worse. Try visiting someone else's Yorkie first to see how you go. Labradoodles were bred to have non-allergenic coats. Good luck - it's worth persevering! Marilyn Brouwer
Biographies are about people, not animals. Most short stories are also about people, but some of them are about animals as well. Most animal stories tend to treat the animals as though they were people, which is different from nonfiction.
No one makes polluted rivers. Animals and people pollute them through natural and technological processes.
Anything you may be allergic to.
