Eric, Do you mind if they also run rabbits now and then? If not, drive down and I will show you six of them and you can take your pick if the digits are right. They range in age from 9 months to 2 1/2 years and are all over 15". I had rather run fox any day than rabbits but sometimes, beagles just have to be beagles.
Foxbeagle.net would be a good place to start.They are in the south but have several associations on the website that are all over.They run fox trials all over the country if you are stickly looking a beagle to run foxes.Hope this helps!!
