Our Donkey Weight Tape has been scientifically researched over many years using over 1,000 donkeys both from the UK and Kenya, with the invaluable help of the Donkey Sanctuary, Sidmouth, Devon and initially Warwickshire College, Moreton Morrell. It was found that a weigh tape specifically for donkeys was required when estimating the weight of a donkey over the age of four. Tapes for horses and ponies skewed the results and were not accurate enough. This was mainly due to differences in digestion, metabolism and weight distribution.
