The compact Welsh Terrier, who looks like a miniature Airedale, is steadier, more sensible, and less excitable than some terriers, yet still full of energy and drive.
The more exercise you can offer, the better. Always alert and ready for a game, his inquisitiveness and tenacity can get him into tight spots.
Welsh Terriers are more amiable with other dogs than some terriers, but they won't back down if challenged. Most Welsh Terriers are friendly and outgoing with everyone, though proper socialization is important to develop this self-confidence. The alert Welsh Terrier can be counted on to sound the alert when anything is amiss; in fact, excessive barking may need to be controlled.
