Behavior

Although often mistaken for a Jack Russell Terrier, the Rat Terrier has a different profile and a very different temperament. Rat Terriers are sleeker in musculature, finer of bone, and have a more refined head. They always have a short single coat, i.e., they are never wire coated.

Rat Terriers tend to be less aggressive than Jack Russells; while they have a definite terrier personality they also have an "off switch" and love lounging on the sofa in a lap as much as tearing about the yard. Rat Terriers are normally cheerful dogs, and they tend to be calmer and more sensitive than Jack Russells to changes in their environment, owner's moods, or to unexpected noises, people, and activities. The "social sensitivity" of Rat Terriers makes them very trainable and easier to live with for the average pet owner, but it also means that extensive socialization from an early age is critical. Proper socialization of a Rat Terrier puppy includes exposing the animal to a wide variety of people and places, particularly during the first three months of life. Like most active and intelligent breeds, Rat Terriers tend to be happier when they receive a great deal of mental stimulation and exercise.

Rat Terriers are short haired dogs that shed a lot. The dog sheds heavily in spring and fall and also during the heat cycle. After whelping the dog shed a lot too. During these times the coat must be frequently brushed with a rubber curry mitt or a soft brush to remove dead hair. Some owners vacuum the hair for about 15 seconds. This removes dead hair more effectively.

The dog may be bathed occasionally but ensure that it is thoroughly rinsed. Nails would need to be trimmed regularly. Be careful of using dog cologne for this breed is known to have allergies. Bluing the fur or conditioning often results in rashes and itchiness.

Behavior

Toy Fox Terriers, like many active and intelligent breeds, can learn to respond to a number of words. Toy Fox Terriers were used commonly in circus shows by clowns, and they are said to make great companions for owners with a good sense of humor. As a terrier breed, they are often active, though perhaps not as active as the Jack Russell Terrier, and are said to be well suited for older owners. They are quite trainable and often cited as making wonderful companions for people with disabilities. They are also very lovable and loyal to their owners. In addition, dogs of this breed tend not to bark very much if they are trained well.

Toy Fox Terriers adapt well to apartment life but love to have room to run. They are active indoors and will do without a yard, as they can usually take care of their own exercise needs. They often have trouble tolerating cold weather without careful acclimation. The Toy Fox Terrier is easy to groom, although grooming is generally seen as unneeded due to how short the hairs are (under a centimetre in length most of the time). Sometimes, it is necessary to comb and brush the coat. The hairs shed very frequently.
