A couple of years ago we bought a filly while she was still nursing. Her bite had been right on at birth. Dam and Sire both have perfect bites. We picked her up after weaning and a short time later were disheartened to see that her bite had shifted off. Over the winter it progressed until it was really bad. She was checked for hooks etc. and was fine. Her bite was way off for a year, and then some friends came looking for a mini as a pet. We showed them two, a colt and this filly. I explained that the filly's bite was off and she would be sold without papers, and opened her mouth to show them. I darn near fell over - her bite was near perfect. I held my breath until they chose the colt, and the filly came off my sale page about an hour later!
She did at one point require the front lower teeth filing a bit as they had grown up in front and were preventing the upper jaw from coming forward. Worked like a charm.
Her bite went from perfect, to bad, to almost perfect again, and she is not finished growing so there is room for improvement yet.
It taught me a lesson about making hasty decisions based on a growing animals bite!
