Miniature Schnauzer

The Mini Ratzer is a combination of the Miniature Schnauzer and the Rat Terrier, which are both small dogs. This hybrid can range in size because the Rat Terrier comes in both miniature and standard sizes but they are usually about 11 to 15 inches tall and weigh about 20 pounds. They have a short, thick, wiry coat that can be just about any color mixed with white. The Mini Ratzer makes a great family pet because they love children and other animals. However, do not leave them alone with young children or small animals like hamsters or guinea pigs.

Mini Ratzer Breed History

Although the hybrid Mini Ratzer has not been around long, you can look at the histories of the parent breeds for an idea as to their history. The Miniature Schnauzer is of German descent and was the smallest and most popular Schnauzer. They were discovered as an excellent rat hunter in the 1800s and were considered working dogs in Europe and other countries. However, in the United States, they are grouped with the Terriers, unlike their larger relatives, the Giant and Standard Schauzers. They were originally called Wirehaired Pinschers and just continued to stay in the Terrier group even after their name change. The Miniature Schnauzer is thought to have been bred from smaller Standard Schnauzers, Toy Poodles, and Affenpinschers. Their name, Schnauzer, means small beard, regarding the beard they have that covers their muzzle, making them look like an old man. In 1926, the Miniature Schnauzer was officially recognized by the American Kennel Club and is now the 17th most popular dog breed in America. The Rat Terrier is one of very few American breeds and they were developed as a small vermin hunter in the 1800s from a mix of the Beagle, Greyhound, Whippet, Fox Terrier, Manchester Terrier, English White Terrier, and Bull Terrier. The breed is well-known for its excellent scenting ability, speed, and friendly disposition. By the 1900s, the Rat Terrier was one of the most popular dog breeds found working on American farms. Theodore Roosevelt had a few Rat Terriers and brought them to the White House when he was president and his dogs were called “Teddy’s Terriers.” Strangely enough, they were not officially recognized by the American Kennel Club until 2013, where they are the 96th most popular breed of dog.


Mini Ratzer Breed Appearance

Unlike most dogs, the Mini Ratzer can have almost any color eyes including brown, hazel, green, gray, or blue. Their nose is usually black but may be brown in lighter colored dogs. Their coat may be just about any color too such as black, gray, brown, red, white, sable, brindle, cream, pied, or fawn. They can vary quite a bit in size, depending on whether the Rat Terrier is a standard or small size. These dogs have triangle shaped ears that perk up when listening, a slight beard, small head, and short legs. Their tail is usually medium length and curves up over the back.

Mini Ratzer Breed Maintenance

Your Mini Ratzer will need to be brushed at least two or three times per week to prevent excess shedding and promote good circulation. Because of their wiry fur, your dog will need his coat stripped every six to eight weeks. You can do this with a stripping tool or by hand by pulling out the dead hairs individually to keep their coat healthy. Once a week, you will need to clean your Mini Ratzer’s ears and check them for mites, excess wax, and other debris. In addition, you should trim your dog’s toenails with nail clippers every six weeks or when you can hear them clicking on the floor.

Mini Ratzer Temperament

The Mini Ratzer is a fun-loving and lively dog that enjoys being with people all the time. They are good watchdogs too and will protect their family from anything they see as a risk. While they do like kids and other pets, they should be watched closely with young children and they may chase small pets like rabbits and guinea pigs. This breed is easy to train and learns quickly so they are good first pets for someone who has not owned a dog before. They listen well and usually do not have any obedience problems unless they are not trained properly.

Mini Ratzer Activity Requirements

The Mini Ratzer has a lot of excess energy and will need approximately one hour to 90 minutes of exercise daily. If they do not get enough physical activity, they can start to become nervous, anxious, or bored. Once that happens, they may become aggressive or develop bad habits like barking too much or chewing on things. Your Mini Ratzer is an excellent hunting companion so if you enjoy hunting, that is a good activity for you both. Some of the other activities your Mini Ratzer may enjoy are playing with other dogs at the dog park, taking a brisk walk around the neighborhood, swimming, hiking, or playing fetch.
