From Wales, where it developed as a Terrier breed, the Welsh Terrier runs on energy rated 4/5, and that drive sets the exercise bill: 45 to 90 minutes a day for an adult. At 19 to 20 lb the Welsh Terrier has the frame for its minutes; the owner's schedule is the only real variable.
Hills, sand and swimming raise the value of a Welsh Terrier minute: resistance work tires a fit adult in half the flat time. Working bred energy at 4/5 does not switch off indoors unless the day has genuinely spent it.
For the record's growth table: the Welsh Terrier passes 8 weeks at about 3 to 3 lb, 6 months at about 11 to 12 lb, 9 months at about 15 to 16 lb, and tops out at 19 to 20 lb and 14 to 17 inches. The standard accepts a range of colors and patterns, and individual markings vary a lot. The breed belongs to the Terrier group and its home ground is Wales.
Under exercise is the root of most Welsh Terrier behaviour complaints presenters bring to trainers, ahead of any question of character or breeding.
By the numbers: a small dog standing 14 to 17 inches, weighing 19 to 20 lb, living 12 to 15 years, with insurance typically $28 to $53 a month. The detail on this page hangs off those figures.
Projects are the terrier contract: provide digging, tug and scent games or the garden provides them. Recall needs honest management around wildlife. A worked Welshie is a merry, affectionate companion with a comedian's timing; an unworked one is a sparkling, stubborn redesign service. Sports like agility and earthdog suit the breed perfectly and burn the energy constructively. Heat is the hard limit for a Welsh Terrier: panting that will not settle or disorientation are stop now signs, never push through signs.
A second dog is not an exercise plan for a Welsh Terrier: playmates help, but the diary of walks and training still belongs to the owner.
A 3/5 Welsh Terrier will not embarrass anyone at classes, and will not top them either; steady is the word. Priorities are recall, managed honestly around game; lead manners; a settle; polite dog behaviour from early socialisation; and cooperative care for the grooming table and teeth.
Track minutes honestly for one week before judging a Welsh Terrier hyperactive; most owners find the diary, not the dog, was the optimistic one.
The energy goes somewhere: chewing, digging, barking and general household redecoration are the usual outlets for a breed whose energy scores 4/5. Most behaviour complaints about the Welsh Terrier trace back to an exercise and occupation deficit rather than character.
Essentially yes: the 45 to 90 minutes are a daily figure for an adult, and dogs do not bank rest days the way people imagine. Illness, extreme weather and vet orders are the legitimate exceptions; a quiet day now and then is covered by indoor games and training.
The 45 to 90 minutes stay constant; the delivery changes. Summer moves the work to cooler hours for a Welsh Terrier, winter adds indoor games when daylight shrinks, and neither season cancels the bill.
Coat questions for the Welsh Terrier: how much hair, how much work and what the routine really looks like.
Two breeds, one decision: the honest differences that matter day to day.
