Interesting Animal - Jack

Jack, a Yorkshire Terrier, is the oldest living dog in Britain.

(At 117 years old (in dog years), he still looks like a puppy.  He will be the eighth-oldest dog of all time if his age can be proven to Guinness World Records.

There are different formulas for calculating dog years. Alot of people multiply by 7, but dogs are mature by the age of 2, so some calculate it by allowing 10.5 dog years per human year for the first 2 years, then 4 dog years per human year for each year after that.

According to: http://www.onlineconversion.com/dogyears.htm, Laika is a mere 57, but according to http://www.pedigree.com/all-things-dog/dog-age-calculator/ she is 70 years old. Guess which one she prefers?)
