While the exact origins are not clear, the Harrier is believed to have been bred down in size from theEnglish Foxhound. While smaller than the Foxhound, it is larger than theBeagle.
The breed has existed in America since Colonial times. The breed was developed primarily to hunt hare, hence the name, and can also do well with the fox.
The dogs became popular in England due to their slower pace; hunters were able to keep up with them on foot. The dogs had superior stamina in the field, with excellent noses. The breed is more popular in England working in packs, and is still rare in the USA. The Harrier was recognized by the AKC in 1885.
