At least seven breeds were used to create the rat terrier, including beagles, smooth fox terriers, old English white terriers, Manchester terriers, bull terriers, whippets, and Italian greyhounds.

Rat terriers are brilliant dogs, but they can be very stubborn. This breed was first developed by early American farmers who wanted a dog who could kill rodents, and they are very talented at burrowing and digging. The standard rat terrier stands between 13-and-18 inches tall. This dog is vigilant, and it will often alert its owners to unusual happenings. The coat on the rat terrier is always made up of more than one color.

A loyal rat terrier is a serious dog that will want to be with you constantly. They are a happy breed that would love to be a trusted member of your family.

Rat Terriers Common Health Issues

Rat terriers are usually healthy dogs, but there are some common health issues that you may want to prepare for if you add one to your family. Hip dysplasia occurs when the ball of the hip no longer fits properly in the socket. It can affect older rat terriers’ quality of life as they have a hard time getting around. Another issue that may occur is Patellar luxation, which means that the kneecap becomes loose. Additionally, rat terriers can have Legg-Calve-Perthes disease, where the blood does not circulate properly to the hip joint, and the bone dies. Remember that getting a mixed breed animal, like those crossed with mini breeds, can add additional health problems. In some rat terriers, the most common health issues are:

  • Hip dysplasia
  • Patellar luxation
  • Legg-Calve-Perthes disease

Another personality trait that you will notice in this breed is that they are exceptionally watchful and loyal. They take their jobs of keeping dangers away very seriously. This can sometimes lead to nervous behavior. Therefore, they may not make the best dogs for families with young children unless you are willing to supervise them and introduce the child to the dog properly.

Rat terriers are independent dogs. Once they decide that they want to do something, almost nothing can stand in their way. Be sure to spend time giving your rat terrier things to keep them occupied, or you may notice destructive behaviors. Overcome your dog’s stubbornness trait by being firm in your training so that the dog knows who is in charge. Use their independent personality to train them for a task that they need to complete each day.

How To Take Care of Rat Terriers

You need to take care of your rat terrier pet mentally and physically. You must give your pet the correct type of diet. Rat terrier puppies need a different diet than older dogs. It is also vital that you train them and exercise them regularly. Proper care often lengthens their lifespan. Regular brushing helps stop them from shedding all over your home.

Rat Terrier Food and Diet

Rat terrier puppy food: Since rat terriers tend to have bone issues, you must feed a puppy food that is high in calcium as it is the building block of strong bones. Until your rat terrier pup is 12 weeks old, they need to be fed four times a day. Between three and six months, you can feed the puppy three meals a day. Then, cut back to two meals a day if the puppy is growing properly.

Rat terrier adult food: Rat terriers tend to get obese quickly. Feeding your dog twice a day can help keep them at the proper weight. Most rat terriers need about 1 cup of food daily, but it depends on their metabolism and the amount of exercise they get. You should be able to see where their waist is and feel but not see their ribs.

Rat Terrier Maintenance And Grooming

Rat terriers shed lightly throughout the year, and you will notice more shedding in the spring and fall. Use a soft brush or a rubber grooming mitt to brush the dog weekly. When your rat terrier has been digging, be sure to give him a bath using a gentle dog shampoo. Plan on trimming his nails about once a month.

Rat Terrier Training

Rat terriers love to please their owners, but they can be a little stubborn. Positive reinforcement usually works well with them. Start as soon as possible to socialize your rat terrier as they can be shy around strangers.

Rat Terrier Exercise

Rat terriers need 30-to-60 minutes of daily exercise. They have a powerful prey drive, so be sure to choose where you let them off leash carefully. Take them for a daily walk and enjoy their companionship. This breed can be trained for a variety of competitions, including agility training.

Rat Terrier Puppies

You must socialize your rat terrier puppy early. Their prey instinct means that they see other small animals as prey to be caught without proper training. They often take their job as a watchdog seriously, so they can also see strangers as something to worry about without proper early training. Breeders and rescues are often good sources for advice.

Rat Terriers And Children

These dogs have a no-nonsense temperament, which may not make them the best dogs for families with young children. Once the child is old enough to understand how to treat the dog properly, you will likely discover that they quickly become best buddies.
