Dogs and cats age faster than humans. Veterinarians consider a 7-year old dog or an 8-year old cat older, a euphemism for old.
Now you may have dogs and cats older than 7 or 8 and they still act
like youngsters, or you really have youngsters who drag a bit like an
older pet would. Of course, they're all different, but there are
certain heath supplements that help keep your pets young, and even if
they are not acting old, these three types of supplements will help
protect or revitalize certain functions.
