It's the deal you make having pets - you know they don't live for very long and you will be devastated when you lose them. But the fun, love, companionship and joy they bring is worth the pain at the end and the massive hole they invariably leave. It's a privilege that pets choose to share their lives with us.
Just like people, dogs and cats can show allergic symptoms when their immune systems begin to recognise certain everyday substances - or allergens - as dangerous. Even though these allergens are common in most environments and harmless to most animals, pets with allergies will have an extreme reaction to them.
