Black Mouth Cur

35-85 lbs
United States

The Black Mouth Cur is one of the best known of the several Cur type dogs that were developed in the southern part of the United States. They were cultivated from hounds, terrier breeds, and feist dogs to be multipurpose canines that were equally able to perform hunting, herding, and guarding duties for farmers and settlers who often couldn’t afford to support more than one dog at a time and as such were bred for their skills rather than for their appearance. Because of this, there is a great deal of variation from dog to dog in the areas of both coloration and in size. No matter what size they are these dogs have a high activity level and an extremely high prey drive; they will need both physical and mental exercise on a daily basis to prevent problem behaviors from developing.

Black Mouth Cur Breed History

Cur, while originally used to describe an unhealthy or aggressive mongrel dog, may now refer to one of several breeds of dog that were developed as multipurpose farm dogs in the Southern United States. Dogs that fall into the Cur classification were deliberately bred for their varied skills, so it stands to reason that several different breeds of dog with several different skill sets were combined to develop these dogs with little regard given to the animal’s physical appearance. Written records of this type of dog indicate that the Cur has been around since at least the 1700s, and most of them were blends of hound and terrier, with a dash of feist and herding dog thrown in the mix. The first Cur dogs eventually split into several types including the Catahoula Leopard dog, the Mountain Cur, the Treeing Cur, and the Black Mouth Cur. The Black Mouth Cur is one of the older varieties of Cur and is described by author Fred Gipson in his well-known novel “Old Yeller,” although the dog in the movie of the same name was a rescue dog that is believed to be a mix between a Mastiff and a Labrador Retriever. The Black Mouth variety can be distinguished by their characteristic black muzzle as well as the darker pigmentation that extends to the inside of their mouth, with only their tongues remaining pink. This dark pigmentation has led many experts to believe that the Black Mouth Cur, in particular, may have had a significant contribution from the English Mastiff, although that has not been substantiated at this time. 

Black Mouth Cur Breed Appearance

The Black Mouth Cur is a medium-to-large dog that stands between 16 and 25 inches tall and can be a bit heftier than most varieties of cur as they can reach up to 95 pounds. They are slightly longer than they are tall and they have a particularly broad, muscular chest and a slightly arched loin. The legs of the Black Mouth Cur are strong and straight and many of these dogs have webbing between their toes. Their heads tend to be on the large side with a broad, flat skull and a broad muzzle with a particularly well-defined underjaw. The muzzle and the inside of the mouth are typically colored black, with only the tongue remaining pink and their medium-length, drop-style ears are set high up on the head and hang close to the cheek. Their eyes can come in any shade of brown, green, or yellow; while blue and multicolored eyes do occasionally pop up, they are considered serious faults.

Black Mouth Cur Breed Maintenance

These dogs have relatively easy coats to care for and few grooming difficulties. Bathing should be kept on an “as needed” basis as these dogs can develop problems due to dry skin if they are bathed too frequently. Although they should only need brushing a few times a month to control their shedding and keep their fur healthy, their coats tend to pick up dirt and debris when outdoors, which may require more frequent brushing sessions. Many Black Mouth Curs also shed more heavily during the change of seasons and may require more frequent brushing sessions during those times as well.

Black Mouth Cur Temperament

This breed tends to be fairly sociable with people of all ages, but they should be closely supervised when interacting with smaller children as they can be large and somewhat clumsy on occasion. With proper socialization, they get along reasonably well with other dogs when on neutral territory, but due to their territorial nature, this can sometimes switch to aggression when they are on their own property. They are natural hunters with an extremely high prey drive, so these dogs are not typically recommended for homes with cats and other smaller pets. They should never be left alone in the backyard as they are highly resourceful escape artists and their prey drive is so intense that when given free rein many Black Mouth Curs will bring home “presents” of dead animals for their owners much like outdoor cats, only with larger prey. They are highly intelligent and are excellent problem solvers, but while there are many who take quickly to training some Black Mouth Curs will show no interest at all in being trained and prefer to try and learn things on their own, which can sometimes lead to mischief.  

Black Mouth Cur Activity Requirements

These dogs are generally quite active and need at least an hour of vigorous activity per day as well as a good deal of mental stimulation to keep their curious minds busy. If they are not given enough physical and mental stimulation, this breed can quickly become mischievous and even destructive. Fortunately, the Black Mouth Cur is also an extremely versatile canine and they can be entertained with a number of different activities including herding, tracking, and swimming activities. These dogs are generally too large, active, and territorial to make good apartment dwellers and they are happiest when they have a large yard to run and play in.

Joey was initially timid when we first got him from a shelter. He was also very bitey, which was quite frustrating at first because we have little kids and the bites would draw blood. However, with continuous training with lots of positive reinforcement, he is now a very docile guy at 6 months. He gets hyper in the morning and we play fetch until he tires. Then he naps a lot during the day. He has slept through the night since we got him at 15 weeks old, and he has been potty trained ever since. He learns really quickly with dog treats.

As my first ever dog, I didn't do my research on how much exercise she would need in our apartment. But, she seems content since my husband and I take her out several times a day to either run around with other dogs or for a walk. I am glad we are planning to move to a house with a proper yard. She's a bit dependent but it's very sweet. She's quite cuddly in her own way. She's picking up training pretty well so far. We have only had her for a month

As a rescue from a high-kill SC shelter, our 7-month-old Black Mouth Cur was timid, anti-social with other humans but liked other dogs until she felt safe. Now she's wild, does the "BMC Zoomies" around the house, loves my boyfriend but has become somewhat aggressive towards me who gives her all her commands in loud tones and reprimands her for chewing and jumping on furniture. She has begun growling and biting me. She's sweet half the time. I walk her 3 times a day. My boyfriend and his older son walk her the rest of the time. I'm not accustomed to an adversarial relationship with a dog. I've been the dog whisperer all of my life. I've had Collies all of my childhood and adulthood until I rescued a Labrador from my brother 16 years ago. I'm heartbroken. I hope it changes.

She has developed an allergy as she has gotten older and even with the help of a veterinary dermatologist, we are struggling to identify the allergy. She has to get weekly baths because of it. Other than this frustrating issue, she is an absolutely amazing dog and by far the smartest dog I’ve ever had in my life. Keep in mind, my other dog is a Belgian malinois. She is leaps and bounds smarter than he is. Her sense of smell is amazing. I’ve taken her to work (a high school) before and she was great with all kids, even the life skills class that we went to visit. She gets along well with other dogs. She is very vocal, but not in the sense that she barks all day. She makes very different noises based on what she wants, and it’s amazing. She truly loves the heat. If it’s colder than 80 degrees, she is cold. She can run around outside in 200 degree heat all day because she CHOOSES to do so, and will just occasionally run through the kiddie pool to cool her feet off. She has webbed toes but hates swimming.

She is insatiable for exercise but more loving than any dog I've ever met. Maybe getting her right before a nationwide quarantine was less than ideal considering we live in a condo, but she has been great about it. Seriously the best dog I could ever imagine.

She was mistaken at the shelter for a pit bull, which we did not care to bring into our home. BUT, she was so precious at 4 months, we couldn't resist her. Come to find out, when she got a few months older we knew she was NOT a pit bull, not even close. I had started to research and I found her to be a full bred Black Mouth Cur, she is not a mix of any other breed. Our vet's technician confirmed her to be BMC as she owns 2. She is the sweetest puppy and loves everyone, even our male min-pin mix named Dickie who seems to have fallen in love with her! She is much larger (@38 lbs.)than our little guy at 18 pounds but they are compatible and that's what we wanted for both of them. She adjusted very well to family life. We can't imagine why anyone would give her up at 4 months but we are so happy they did! She is our little girl now.
