Small and fast; easy to lift but hard to catch when chasing wildlife. Fence security matters more than square footage.

Medium and solid with real muscle. Knocks things over without meaning to; needs sturdy toys and strong leash skills.

Often reaches teens with safe lifestyles and dental care. Lens luxation and other genetic topics appear in responsible breeding programs.

Mid-range lifespan for a medium dog; kidney and heart discussions exist in the breed. Weight control supports longevity.

Extremely high for typical individuals; digging, barking, and escaping appear when bored. Sports and puzzles are baseline care.

Smooth or broken coats are relatively easy; some shedding. Broken coats may need hand-stripping input from a groomer.

Short coat is simple to bathe; shedding is noticeable. Skin allergies can occur; work with your vet if itching persists.

Clever but independent; excels when training feels like a game. Recall off prey is a lifelong project for many dogs.

Smart and motivated by people; needs fair rules and early socialization. Stubborn streaks appear if training feels unfair.

Fun for active families who supervise around small pets. Nipping during play can alarm parents without terrier experience.

Discuss patellas, eye issues, and dental care. Leg injuries happen when jumps and heights are not managed.

Deafness in white dogs, kidney concerns, and heart screening are breed discussion points with ethical breeders.

Small food bills; replacement toys and secure fencing may be the hidden costs. Vet bills for bite wounds if wildlife chasing goes wrong.

Medium-dog feeding and durable gear costs. Possible specialist care if inherited conditions appear in certain lines.
