Size and Weight

The black mouth cur varies quite a bit in size from region to region and breeder to breeder. Consequently, this breed has a wide range of weights and heights. Male Curs stand between 18 and 25 inches at the shoulder and weigh anywhere from 40 to 95 pounds. Females are slightly smaller, standing 16 to 23 inches tall and weighing 35 to 85 pounds.

Height (Male):18 to 25 inches
Height (Female):40 to 95 pounds
Weight (Male):16 to 23 inches

Common Health Issues

Due to its mixed and varied lineage, the black mouth cur is a rugged, healthy dog. Like many dogs, it can be susceptible to joint-related issues, such as elbow and hip dysplasia. Curs need a great deal of exercise and are prey-driven, so they may be prone to obesity if not active enough. Many can also develop allergies which can cause skin and ear irritations. Finally, some have been diagnosed with epilepsy, so if you notice your dog shaking, vomiting, or having balance issues, contact your vet immediately.

Black Mouth Cur Temperament

This dog is affectionate, loyal, and hardworking. They have a high energy level that has them constantly looking for something to do. While they bond well with families and children, their need for activity, exercise, and engagement makes them more appropriate as farm or hunting dogs. Their rambunctious and playful personality can make them a hit with kids but can also lead to collisions, bumps, and bruises with smaller children.

How To Take Care of a Black Mouth Cur  

Maintenance and Grooming

Grooming this breed is not a difficult chore. The Cur is a rugged dog with a short wash-and-wear coat. If the coat gets dirty, wipe it down. Brush it every week or so; otherwise, the dog can be bathed whenever it smells bit doggy. If the dog is not working, clip its nails every few weeks. Check its skin and ears for irritation and debris, wiping down folds in the skin if necessary. Finally, brush the dog’s teeth a few times a week.

Training

Intelligent and independent, this dog can be challenging to train. Keep sessions short, energetic, and interesting. The Cur responds best to a firm but positive approach; it does not respond well to harsh treatment or speech.

Exercise

The black mouth cur is a highly energetic dog that requires at least an hour of intense activity if not two. A hardworking dog, the Cur is bred for herding, hunting, and guarding; it is not a dog for lying around the house. Even though a large enclosed yard is good for exercise purposes, it’s best not to leave the dog in the yard unattended as it will chase anything that runs and can escape.

Puppies

Socialization should begin as soon as the puppy arrives home. Take it with you to new places and introduce the little pup to new people and other dogs. This breed can be territorial and rambunctious; you must socialize the dog well from a young age. Puppy kindergarten is a good idea as soon as it has been fully vaccinated. Introduce your Cur to your children and other dogs. Bringing a black mouth cur into a home with cats or other small pets is not a good idea because the cur will treat them as prey.

Black Mouth Curs and Children

These dogs and children get along well, and curs have been known to be highly protective of children. Curs have even been known to step in when children are disciplined, so that’s something to be aware of. Socialize the dog early with children to get them to bond with one another. Also, teach the children how to interact with a dog, so they do not poke, prod, and pull at it. They play rough, so they are probably not a good match for small children. Finally, children should never be left unsupervised with an untrained dog, and small children should never be left alone with any dog, trained or otherwise.
