Indoors it can be housed in vivaria from 150cm long by 60cm deep by 60cm high, as a minimum for an adult pair. The sides of the cage should be opaque except for the front glass to give the dragon some sense of security. The dragon is likely to be very nervous and damage itself in cages made entirely of glass.
According to this model, a Bulldog will age an average of 13 years per human year whereas a Miniature Dachshund only ages about four years. Unfortunately they only calculated the 3+ year ratio for a handful of dog breeds, but this means that my 1-year old Border Collie, Scuttle, is about 10.5 in human years!
How does the age of a horse compare to the age of a human being? A horse year is equal to 6 1/2 human years for the first 3 years of the horse's life. At the horse age of three the equivalent changes and is approximately 5 years to man. From 4 the horse year equivalency changes to 2 1/2 years. If your horse lives to be 36 horse years the human equivalency in years would be 100 1/2 years!
