He doesn't look like a 'show type' beagle to me although the pics aren't too good
Many breeds have a working type as well as a show type, so yours could be a Harrier which is the working type of Beagle - once used to hunt hares in packs but now (if any packs exist) solely used for rabbits.
Harriers are taller and a little longer than beagles... One "Beagle" I knew which was certainly a mis-sold Harrier, was very tall and rangy (as well as having a very high prey drive, zero recall and never stopped barking!).
Many years ago when I was a kid my family were invited out beagling with a local pack - it involved a many-mile walk through mud, water, ditches, over barbed wire, gates, through more mud, stumbling over ploughed fields, more hedges, brambles, scratches and we only caught up with the pack about twice! The pack was novice so nothing was caught or even chased, and while they were supposed to go after hare, they were far more interested in stuffing their noses down rabbit holes and telling each other how nice it smelled.
