Do other an­i­mals get al­ler­gies?

BBC Earth (Asia) - - Q & A -

Yes. Cats, dogs and horses can all de­velop al­ler­gies in much the same way that hu­mans do. There are three main kinds of al­lergy in an­i­mals – food, flea bites and en­vi­ron­men­tal al­ler­gies such as grass pollen and mould spores. Al­ler­gies seem to be much more com­mon in do­mes­tic pets than in wild an­i­mals or farm an­i­mals that spend most of their time out­doors. This may be be­cause the more hy­gienic con­di­tions in hu­man houses leave less work for the im­mune sys­tem and so it gets in­ap­pro­pri­ately sen­si­tised to nor­mally harm­less par­ti­cles in the en­vi­ron­ment. An­i­mals typ­i­cally get more al­ler­gic as they get older. LV
