Their sense of smell for tracking is second only to that of the Bloodhound. The name Basset is derived from the French word bas, meaning "low", with the attenuating suffix -et, together meaning "rather low". Basset Hounds are usually two or three colored mix. Basset's are really good with children and usually aren't that aggressive.

The Old English Sheep Dog

The Old English Sheep Dogis a large breed of dog which was developed in England from early herding types of dog. The Old English Sheepdog can grow a very long coat, with fur covering the face and eyes. Obsolete names of the breed include Shepherd's Dog and bob-tailed sheep-dog. It is still nicknamed Bob-tail (or Bobtail) because historically, the tail was traditionally cut off in this breed. Great with kids, but it also sheds a lot.
