On a weigh bridge in january my 17.2hh danish wb x TB weighed 730kg and he has been on box rest for 2 weeks + after summer grass so i would expect he is 750kg+ atm.
After having both mine weighed on proper weigh machine at weekend I will never believe a weightape again!!! 16hh WBx came in nearly 30kg lighter than my 16.1 tb. I was gobsmacked!!! WBx was 578kg & tb was 606kg, both defo don't need to lose any weight.
My pony used to get seriously fat (greedy 14hh welsh x!) And a tape would show her to be about 450kg and she had a very big belly! But when she went to the vets, she was in fab condition and looked the perfect weight and the weigh bridge said she was 460kg!
